    摘要: In a process for oligomerizing an olefinic hydrocarbon feedstock, the feedstock is contacted under oligomerization conditions with (a) a first crystalline molecular sieve catalyst and (b) a second catalyst comprising a solid phosphoric acid. The first and second catalysts may be contained in separate reactors or as separate beds in a single reactor.

    摘要: In a process for producing a hydrocarbon composition, a feed comprising at least one C3 to C8 olefin and an olefinic recycle stream rich in C9− hydrocarbons is contacted with a crystalline molecular sieve catalyst having an average crystal size no greater than 0.05 micron and an alpha value between about 100 and about 600 in at least one reaction zone under olefin oligomerization conditions including an inlet temperature between about 150° C. and about 350° C., a pressure of at least 2,860 kPa and a recycle to feed weight ratio of about 0.1 to about 3.0. The contacting produces an oligomerization effluent stream, which is separated into at least a hydrocarbon product stream rich in C9+ hydrocarbons and the olefinic recycle stream.
