- This application claims priority under 35 U.S.C. §119 from U.S. Provisional Application Ser. No. 60/978,586 (filed Oct. 9, 2007), the disclosure of which is incorporated by reference herein for all purposes as if fully set forth.
- This application is related to commonly owned U.S. application Ser. No. ______, (filed concurrently herewith), entitled “COMPOSITIONS FOR CATALYTIC GASIFICATION OF A PETROLEUM COKE”.
- The present invention relates particulate compositions of a crude oil resid-based petroleum coke containing at least two preselected catalytic components, which composition exhibits an efficient, enhanced-yielding gasification to value-added gaseous products, particularly when used in a steady-state integrated gasification process. More particularly, this invention concerns compositions of a petroleum coke loaded with a mixture of (i) an alkali metal component, and (ii) an iron component.

No. 11/832809 (filed 2 Aug. 2007 and entitled “Catalyst-Loaded Coal Compositions, Processes for Preparing Same, and Integrated Processes for Preparation of Methane from Coal”).
- Petroleum coke is a generally solid carbonaceous residue derived from delayed coking or fluid coking a carbon source such as a crude oil resid. Petroleum coke in general has a poorer gasification reactivity, particularly at moderate temperatures, than does bituminous coal due, for example, to its highly crystalline carbon and elevated levels of organic sulfur derived from heavy-gravity oil. Use of catalysts is necessary for improving the lower reactivity of petroleum cokes.
- One advantageous catalytic process for gasifying petroleum cokes to methane and other value-added gaseous products is disclosed in the above-mentioned US2007/0083072A1. This publication discloses the use of alkali metals to catalyze the gasification reaction. While the process disclosed in this publication is generally quite effective, it would be desirable to find alternative catalyst systems with potentially improved gasification activity.
- The present invention is directed to the gasification of a petroleum coke derived from a crude oil resid, for example, by coking processes used for upgrading heavy-gravity residual crude oil, which petroleum coke contains ash but as a minor component, typically about 1.0 wt % or less, and more typically about 0.5 wt % of less, based on the weight of the coke. Typically the ash in such lower-ash cokes predominantly comprises metals such as nickel and vanadium.
- In this context, the present invention is directed to particulate compositions of such petroleum coke containing at least two preselected components that exhibit an efficient, enhanced-yielding gasification to value-added gaseous products. More particularly, the present invention is a particulate composition having a particle distribution size suitable for gasification in a fluidized bed zone, comprising an intimate mixture of (A) a petroleum coke derived from crude oil comprising ash in an amount of about 1.0 wt % or less, based on the weight of the petroleum coke, and (B) a gasification catalyst which under suitable conditions of temperature and pressure and in the presence of steam exhibits gasification activity whereby value added gaseous products are formed, wherein:
- (a) the gasification catalyst comprises (i) a first component which is a source of at least one alkali metal, and (ii) a second component which is a source of iron; and
- (b) the gasification catalyst is present in an amount sufficient to provide, in the particulate composition, a ratio of alkali metal atoms to carbon atoms in the range of from about 0.01 to about 0.1, and a ratio of iron atoms to carbon atoms in the range of from about 0.01 to about 0.1.
- The compositions of the present invention are particularly useful for catalytic gasification of petroleum coke at moderate temperatures, such as disclosed in US2007/0083072A1. Advantageously, compositions and process according to the invention can be readily incorporated into fluidized bed gasification units, and can result in a more cost-effective, high-yielding production of methane gas.
- In this context, the present invention also provides a process for converting petroleum coke to methane, comprising the steps of:
- (1) combining a petroleum coke and a catalyst having steam gasification activity to produce a particulate composition having a particle distribution size suitable for gasification in a fluidized bed zone,
- (2) reacting the particulate composition in a fluidized bed zone in the presence of steam to form gaseous products including methane and one or more of hydrogen, carbon monoxide and other higher hydrocarbons, and
- (3) recovering methane from the gaseous products,
- wherein the particulate composition is as set forth herein.

- The total amount of catalyst loaded is controlled by controlling the concentration of catalyst components in the solution, as well as the contact time, temperature and method, as can be readily determined by those of ordinary skill in the relevant art based on the characteristics of the starting petroleum coke.
- The particulate compositions of the present invention are particularly useful in integrated gasification processes for converting petroleum coke to combustible gases, such as methane.
- Generally, the particulate compositions of the present invention provide a suitable feedstream of catalyst-containing petroleum coke to any steam gasification process. Generally, such steam gasification processes provide a means for the introducing of dry particulate feed into a fluidized bed zone in a gasification reactor. Coke and superheated steam are reacted while in contact with the catalyst having steam gasification activity, to form a raw product gas, comprised of unreacted steam, methane, carbon dioxide, hydrogen, and carbon monoxide, and a particulate residue, or char having catalyst values incorporated therewith. A purge of the char is withdrawn from the gasification reactor. A raw product effluent stream is cooled to condense unreacted steam to form a sour water stream and a stream of cooled raw product gas from which methane and other components such as syngas are recovered.
- The particulate compositions of the present invention are particularly useful for gasification at moderate temperatures of at least about 450° C., or of at least about 600° C. or above, to about 900° C., or to about 750° C., or to about 700° C.; and at pressures of at least about 50 psig, or at least about 200 psig, or at least about 400 psig, to about 1000 psig, or to about 700 psig, or to about 600 psig.
- A preferred process is described in US2007/0083072A1, and reference can be had to that publication for further process details.
- Where the as-received petroleum coke was found to be too damp (i.e. not free-flowing) to be jaw-crushed, it was necessary to first air-dry it in a mechanical-convection oven at 35° C. for an extended period of time. Stage-crushing was performed carefully so as not to generate excessive fines and to maximize the amount of material having particle sizes ranging from about 0.85 to about 1.4 mm.
- Analyses of the petroleum coke samples provided results as follows: 8.9 percent by weight volatile matter and 0.38 percent by weight ash (proximate analysis); metal components in the ash of vanadium 170 mg/kg and nickel 220 mg/kg; carbon 86.3 percent, hydrogen 3.6 percent, nitrogen 1.8 percent, sulfur 6.0 percent and oxygen 2.3 percent (ultimate analysis); and a BET surface area of 2 to 3 m2/g. The atomic ratio of hydrogen to carbon was 0.20, and sulfur to carbon 0.026.
- Compounds of potassium (nitrate, acetate, hydroxide and carbonate) and iron (nitrate, acetate and hydroxide) were used as catalyst precursors in a liquid medium. Preselected amounts were contacted with the petroleum coke by mixing with a rotary evaporator at room temperature or at 0° C. if a water/ethanol solution was used. After separation from the liquid, the wet solid particles were subjected to reduced pressure thereby drying them for gasification.
- Catalysts of about 1 and about 5 mass % of potassium were made, as well as catalysts of about 3 mass % iron. Binary catalysts of combinations of the above were also made.
- Gasification was carried out in a high-pressure apparatus that included a quartz reactor. About 100 mg of the sample was first charged into a platinum cell held in the reactor and then gasified. Typical gasification conditions were as follows: total pressure, 1.0 MPa; partial pressure of H2O, 0.21 MPa, in an atmosphere of high purity argon; temperatures, 750° C. to 900° C.; and reaction times, 2 to 3 hr. Product gas after the removal of H2O and H2S was analyzed on-line with a high-speed micro GC attached with a thermal conductivity detector. In order to determine the amount of H2 produced precisely, argon gas was used as the carrier gas of GC. Coke conversion was estimated by using the weight change before and after gasification and expressed in percent by weight on a catalyst-free basis.
- The conversion of petroleum coke without any catalyst was only about 25 percent at 750° C.; however, it increased with increased temperature and reached about 95 percent at 900° C. Petroleum coke treated with an iron salt (3%) exhibited almost no catalytic effects, irrespective of the temperature. By contrast, potassium compounds promoted the steam gasification even at low loading of 1 percent by weight and the conversion was about 40 percent at 750° C. and about 95 percent at 850° C.
- Gasification of petroleum coke using binary combinations of iron and potassium compounds (1% K/3% Fe) was studied. Petroleum coke overall conversion, after 2 hours at 750° C., without any catalysts was only about 15 percent, which was almost unchanged with iron compounds alone (3%), whereas conversion increased up to about 40-45 percent when a potassium-containing catalyst (5%) was used. An increase in conversion to more than 95% was observed with the use of binary compositions (5% K/3% Fe). A temperature of about 900° C. was required to obtain a conversion that high for uncatalyzed coke, meaning that the binary catalysts demonstrated a lowering of more than 150° C. in gasification temperature.
- The rates of methane formation for the binary catalysts at 750° C. were found to be very high (and highest) under the conditions at the start of the gasification (where the molar ratio of coke/H2O was highest), but decreased rapidly as the time increased (and the molar ratio of coke/H2O decreased).
