摘要: Solid phosphoric acid (SPA) olefin oligomerization process units may be converted to operation with a more environmentally favorable solid catalyst. The SPA units in which a light olefin feed is oligomerized to form gasoline boiling range hydrocarbon product, is converted unit to operation with a molecular sieve based olefin oligomerization catalyst comprising an MWW zeolite material. Besides being more environmentally favorable in use, the MWW based zeolites offer advantages in catalyst cycle life, selectivity and product quality. After loading of the catalyst, the converted unit is operated as a fixed-bed unit by passing the C2-C4 olefinic feed to a fixed bed of the MWW zeolite condensation catalyst, typically at a temperature from 150 to 250° C., a pressure not greater than 7000 kPag, usually less than 4000 kPag and a space velocity up to 30 WHSV. The gasoline boiling range product is notable for a high level of branched chain octenes resulting in high octane quality.

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.
