  • Patent number: 5364997
    Abstract: The present invention relates to a process for upgrading multi-branched C.sub.9 + olefinic and/or paraffinic by-products of heavy hydrocarbon upgrading processes including alkylation, polymerization, and MOGD, to high octane gasoline. Feeds rich in multi-branched C.sub.9 + olefins and/or paraffins are contacted with hydrogen at a pressure in the range of about 200 psig to about 2000 psig in the presence of an unsulfided catalyst composition comprising a low acidity molecular sieve having an Alpha Value of 5 or less. Because of the capability of the catalyst to crack at unsubstituted carbon-carbon bonds, the paraffinic products are more highly branched, and thus higher in octane number than those obtained from conventional dual function hydrocracking catalysts having Alpha Values greater than 5.

  • Patent number: 5284985
    Abstract: The present invention provides a two-stage process for production of high-octane naphtha range isoparaffins from a feed rich in normal and/or slightly branched paraffins. In the first stage, the normal and/or slightly branched paraffins are selectively converted to multi-branched paraffins and then cracked in a second stage to yield naphtha range isoparaffins which can be blended into a high-octane gasoline pool.
