摘要:
Process for converting synthesis gas in naphta by contacting it at 260-315,55 °C and 446,07-6996,09 kPa and at a GHSV of 400-20000 with a catalyst comprising a crystalline acidic aluminosilicate (ZSM-5) having a silica to alumina ratio of at least 12, a pore size greater than 5Å and a constraint index of 1 to 12, a soliceous matrix and iron; this catalyst is prepared by adding the zeolite to a siliceous hydrogel, homogenizing and spray drying the mixture and impregnating it with an iron salt (e.g. the nitrate). The catalyst may contain clay.
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, e.g. extrusion into particles. Said useful class of zeolites is characterized by a silica to alumina mole ration of at least 12 and a Constraint Index in the approximate range of 1 to 12. The final catalyst may include a binder such as alumina and is useful in a variety of processes, particularly xylene isomerisation. ,
摘要:
A catalyst and process for the conversion of synthesis gas to a liquid hydrocarbon product having a boiling range of less than 204-44°C (400°F) at a 90% overhead utilizing a novel catalyst prepared from a water-insoluble organic iron compound. The process 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.
摘要:
A catalyst useful for conversion of synthesis gas to naphtha is prepared by carbon of monoxide treatment of a single particle composite of iron oxide, hydrogel matrix and crystalline zeolite having a silica/alumina ratio greater than 12 and a constraint index of 1 to 12. The iron oxide is present in the composite as a powder, and may be created in situ by oxidation of iron powder. The carbon monoxide may be a component of synthesis gas. The product naphtha is characterised by specific details of boiling range and composition.
