摘要:
A catalyst composition, a process for producing the composition, and a hydrocarbon conversion process for converting a hydrocarbon stream such as, for example, gasoline, to olefins and C.sub.6 to C.sub.8 aromatic hydrocarbons such as toluene and xylenes are disclosed. The catalyst composition comprises a zeolite, a promoter and optionally a binder. The process for producing the composition comprises the steps: (1) combining a zeolite with a promoter under a condition sufficient to produce a modified zeolite; and (2) steaming the modified zeolite. The hydrocarbon conversion process comprises contacting a hydrocarbon stream with the catalyst composition under a condition sufficient to effect the conversion of a hydrocarbon to an olefin and a C.sub.6 to C.sub.8 aromatic hydrocarbon.
摘要:
A catalyst composition and a process of using a catalyst composition for preparing high molecular weight hydrocarbons, such as polymethylene, from a fluid containing hydrogen and carbon monoxide are disclosed. The catalyst composition contains ruthenium and a treated silica support component. The treated silica support component is prepared by a process including contacting a silica support component, such as silicon dioxide, and a treating agent, such as a silicon-containing compound.
