Process for the conversion of lower aliphatic oxygenates to olefins and aromatics with gallium containing ZSM-5 catalyst
TL;DR: In this paper, C 2 -C 5 olefins and aromatics are prepared by catalytic conversion of lower aliphatic C 1 -C 4 oxygenates in the presence of a medium pore gallium containing zeolite catalyst having a ZSM-5 framework at elevated conversion temperatures.
Patent
Aromatisation of aliphatics over gallium-containing zeolites
TL;DR: In this paper, a catalytic process for converting feedstocks containing C 2 to C 12 aliphatic hydrocarbons to aromatics by contacting said feedstocks, under conversion conditions, with a crystalline zeolite catalyst having a constraint index of about 1 to 12 and a silica-alumina ratio of at least 550, and containing a minor amount of an added metal comprising at least 50 weight percent of gallium.
Patent
Crystalline molecular sieve
TL;DR: A synthetic crystalline molecular sieve composition comprises at least 70 % by weight of a crystalline material having the following X-ray diffraction lines: as discussed by the authors Theoretically, it is known that the ratio of the ratio is at most 70% by weight.
Patent
Methanol conversion using reactivated zeolite catalyst materials
TL;DR: In this article, a method of converting methanol into hydrocarbons using ZSM-5 type catalysts has been proposed, which occurs at temperatures from 100 to 1000°C to the extent that at least 10% crystallinity is preserved in the activated product.
