The present invention provides various processes for producing methanol and ethanol, preferably in a mixed alcohol stream. In one embodiment, the invention includes directing syngas to a synthesis zone wherein the syngas contacts a methanol synthesis catalyst and an ethanol synthesis catalyst (either a homologation catalyst or a fuel alcohol synthesis catalyst) under conditions effective to form methanol and ethanol. The methanol and ethanol, in a desired ratio, are directed to an oxygenate to olefin reaction system for conversion thereof to ethylene and propylene in a desired ratio. The invention also relates to processes for varying the weight ratio of ethylene to propylene formed in an oxygenate to olefin reaction system.

Controlling the ratio of ethylene to propylene produced in an oxygenate to olefin conversion process

A process for the alkylation of an aromatic compound with C.sub.2 to C.sub.4 olefin alkylating agent. A process to produce ethylbenzene by reaction of ethylene in stoichiometric or excess amount with benzene in the presence of a zeolite beta catalyst. This process is especially suitable for reaction of dilute ethylene with dilute benzene in a catalytic distillation column.

Alkylation process using zeolite beta

There is provided a process for converting hydrocarbons which utilizes a zeolite bound zeolite catalyst that has enhanced performance when utilized in hydrocarbon conversion processes, e.g., catalytic cracking, alkylation, disproportionation of toluene, isomerization, and transalkylation reactions. The catalyst comprises a first zeolite having particles of greater than about 0.1 micron average particle size and a binder comprising second zeolite particles having an average particle size less than said first particles.
