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. It has also been discovered that the novel process can be conveniently integrated with hydrocarbon catalytic cracking operations in a manner which advantageously utilizes the unsaturated gas plant and main fractionator of the cracking process to facilitate the separation of the products of the novel conversion process.
