摘要:
A method for converting an alcohol to hydrocarbons comprises two serially placed catalysts. The fraction of aromatics is reduced to desired levels. The method comprises: a) contacting the alcohol with a first catalyst on a carrier, said carrier is selected from a mixed oxide and a mesoporous carrier, said first catalyst comprises at least one basic oxide and optionally at least one selected from the group consisting of metals and metal oxides, then b) contacting the resulting mixture from step a) with a second catalyst wherein said second catalyst is an etched metal loaded zeolite catalyst wherein the etched metal loaded zeolite catalyst is manufactured with a method comprising etching with subsequent loading of metal onto the catalyst, wherein the metal is in the form of nanoparticles, and wherein at least two different metals are loaded onto the etched zeolite catalyst. The hydrocarbons are recovered and used for instance for fuel including gasoline, kerosene, diesel, and jet propellant, and jet fuel. Naturally, other uses of hydrocarbons should not be excluded.

摘要:
Methods of converting olefins include the steps of providing propane and isobutane to a dehydrogenation reactor to produce effluent that is sequentially cooled, compressed and passed to a distillation zone under conditions to fractionate propylene, isobutylene, butane and propane from the effluent. Propylene, isobutylene, butane and propane are separated in a distillation zone to produce a propylene concentrate stream, an isobutylene concentrate steam, a propane recycle stream, and a butane recycle. The propane and isobutane are recycled back into the feed stream. The propylene concentrate stream and the isobutylene concentrate stream are passed to an oligomerization reactor to produce an oligomer product mixture that includes the olefin conversion products. The oligomer product mixture is then passed to the distillation column where olefin conversion product is separated as oligomer product.
