An improved processing technique is provided for conversion of olefins of 2 to 4 carbon atoms to product comprising high octane gasoline components. Embodiments of the present improved processing technique include conversion of light olefins to high octane olefinic gasoline components, and conversion of light olefins to high octane aromatic gasoline components. The improved technique comprises contacting an appropriate light olefin feedstock with a catalyst comprising a crystalline aluminosilicate zeolite characterized by a silica/alumina mole ratio of at least 12 and a constraint index, hereinafter defined, within the approximate range of 1 to 12 in the presence of a relatively large amount of co-fed water. The amount of co-fed water is maintained at from about 0.5 to about 15 moles of water/mole of olefin feedstock.
In a catalytic process for converting olefin feedstock comprising at least one olefin of from 2 to 4 carbon atoms to gasoline components, the improvement which comprises contacting said olefin feedstock with a catalyst comprising a crystalline aluminosilicate zeolite, characterized by a silica/alumina mole ratio of at least 12 and a constraint index within the approximate range of 1 to 12, in the presence of from 0.5 to about 15 moles of water/mole of olefin feedstock, said contacting at a temperature of from about 450.degree. F. to about 800.degree. F. a pressure of from about atmospheric to about 1000 psig and a weight hourly space velocity of from about 0.2 hr.sup.-1 to about 20 hr.sup.-1.
