  • Patent number: 5202015
    Abstract: Process conditions and process configuration have been discovered for the concurrent but independent catalytic reaction of waxy distillate and light olefins feedstocks that simultaneously results in the dewaxing of distillate feedstock and the oligomerization of light olefins to produce olefinic gasoline. In the novel process, under the conditions discovered, the opposing reactions of molecular weight reduction, as exemplified by waxy n-paraffin cracking, and molecular weight growth, as exemplified by olefin oligomerization, have been found to compatibly coexist to achieve the sought after objective of producing olefinic gasoline while dewaxing distillate in a single conversion step. Partial desulfurization and denitrogenation of the distillate feed also occurs.

    Abstract: A process is described for the catalytic cracking of a hydrocarbon feedstream involving the use of an acid catalyst comprising a catalytic component selected from the group consisting of oxides of tungsten, niobium and mixtures thereof and tungsten or niobium oxides in combination with one or more additional metal oxides selected from the group consisting of tantalum oxide, hafnium oxide, chromium oxide, titanium oxide and zirconium oxide on supports, wherein (1) the feedstream is catalytically cracked by being contacted with said catalyst at a temperature and for a time (optionally, in combination with H.sub.2 O), sufficient to crack the hydrocarbon yielding a cracked product and a deactivated catalyst and (2) subjecting the deactivated catalyst to gasification conditions consisting of (A) partial oxidative combustion to produce a low BTU gas rich in CO or, (B) the addition of steam to produce a gas rich in H.sub.2, or both, with the recirculation of the decoked catalyst back to the first step.

  • Patent number: 4233139
    Abstract: It has been discovered and forms the basis of the disclosure that various acid catalyzed hydrocarbon conversion processes such as catalytic cracking of gas oil; xylene isomerization; toluene disproportionation; dealkylation of aromatics; ethylene, butylene, isobutylene, propylene polymerization; olefin isomerization; alcohol dehydration; olefin hydration; alkylation; heavy ends cat cracking, etc. are dramatically improved insofar as percent conversion, and selectivity are concerned by the use of a catalyst selected from the group consisting of the oxides of tungsten, niobium and mixtures thereof, and tungsten or niobium oxides in combination with one or more additional metal oxides selected from the group consisting of tantalum oxide, hafnium oxide, chromium oxide, titanium oxide and zirconium oxide, supported on an inorganic refractory oxide support. These catalysts may be prepared by the methods known in the art, i.e., incipient wetness, impregnation, coprecipitation, etc.
