摘要:
A method of preparing aromatics processing catalysts which comprises incorporating a noble metal with a member or members of a useful class of zeolites, with such incorporation occurring after zeolite crystallization, but prior to final catalyst particle formation, i.e. extrusion into particles. Said useful class of zeolites is characterized by a silica to alumina mole ratio of at least 12 and a Constraint Index in the approximate range of 1 to 12.
摘要:
A method is disclosed for the conversion of synthesis gas to a liquid hydrocarbon product having a boiling point range maximum of less than 400.degree. F. at a 90% overhead and being a predominantly olefinic product. The novel method involves contacting synthesis gas with a single particle catalyst containing cobalt, a crystalline acidic aluminosilicate zeolite having a silica-to-alumina ratio of at least 12, a pore size greater than about 5 Angstrom units, and a constraint index of about 1 to 12, and a siliceous matrix. The catalyst does not contain promoters and the alumina content of the matrix is severely restricted.

A method is disclosed for the conversion of synthesis gas to a liquid hydrocarbon product having a boiling range of less than 400.degree. F. at a 90% overhead utilizing a novel catalyst prepared from finely divided iron powder or iron oxide. The novel method involves contacting synthesis gas with a single particle catalyst containing iron, a crystalline acidic aluminosilicate zeolite having a silica-to-alumina ratio of at least 12, a pore size greater than about 5 Angstrom units, and a constraint index of about 1 to 12, and a matrix. The catalyst does not contain promoters.
