Abstract

The present invention relates to particulate compositions of a lower ash type petroleum coke containing at least two preselected components (alkali metal and iron) that exhibit an efficient, enhanced-yielding gasification to value added gaseous products, particularly when used in a steady-state integrated gasification process. The compositions of the present invention are particularly useful for catalytic gasification of petroleum coke at moderate temperatures ranging from about 450° C. to about 900° C. Advantageously, the compositions can be readily incorporated into fluidized bed gasification units, and can result in a cost-effective, high-yielding production of methane gas from petroleum coke.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]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.[0002]This application is related to commonly owned U.S. application Ser. No. ______, (filed concurrently herewith), entitled “COMPOSITIONS FOR CATALYTIC GASIFICATION OF A PETROLEUM COKE”.FIELD OF THE INVENTION[0003]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.[0004]The pres...
