Abstract
Normally gaseous olefins are converted to hydrocarbons of higher molecular weight by contact with a polymerizing catalyst consisting of a solid phosphoric acid catalyst or a composite of silica with one or more of the oxides alumina, thoria, titania and zirconia under polymerizing conditions in the presence of an added substantially non - olefinic liquid hydrocarbon diluent comprising alkyl aromatic and/or naphthenic hydrocarbons which is substantially unreactive under the reaction conditions so that a substantially aliphatic product is formed. Preferably, a mixture of the hydrocarbon diluent with a minor proportion by weight of gaseous olefin is passed continuously at a space velocity of 2-4 liquid volumes per volume of catalyst space per hour, temperatures being about 200-500 DEG C., and pressures 13.5-70 atmos. Regulated p amounts of water or compounds yielding it may be added. Gas containing ethylene, propylene or butylene may be mixed with at least its own weight of a kerosene or other hydrocarbon which is largely of naphthenic and alkyl aromatic character and passed over a phosphoric acid-kieselguhr at about 300-400 DEG C. and 34 atmos. Ethylene is converted to paraffins and olefins of 4-8 carbon atoms including isobutane, butene, 2,3-dimethyl-butane and butene, while propylene yields similar products of 4-9 carbon atoms. Higher boiling products may remain in the liquid diluent which may be recycled or cracked to convert them to olefins for charging to the process. Olefins produced may be dehydrogenated to diolefins or isomerized while paraffins may also be dehydrogenated. In examples, a kerosene free from olefins and consisting largely of naphthenes, and alkyl aromatics and of less than 50 per cent paraffins is mixed with ethylene and treated with a solid phosphoric acid catalyst to yield a gas largely isobutane and butenes, and C5-C7 fractions, the C6 being mainly 2,3-dimethylbutene-2. Propylene is converted similarly using phosphoric acid-kieselguhr or silica-alumina as catalyst.
