Title:
【発明の名称】硫黄を有する複素環式分子の生触媒的脱硫のための連続的方法
Document Type and Number:
Japanese Patent JPH06507436
Kind Code:
A
Abstract:
A continuous cyclic process for desulfurizing a petroleum liquid which contains organic sulfur molecules, a significant portion of which are comprised of sulfur-bearing heterocycles. This process involves oxygenating the petroleum liquid and treating it with a biocatalyst capable of catalyzing the sulfur-specific oxidative cleavage of organic carbon-sulfur bonds in sulfur-bearing aromatic heterocyclic molecules such as dibenzothiophene. a particularly preferred biocatalyst is a culture of mutant Rhodococcous rhodocrous bacteria, ATCC No. 53968. In the present process, the activity of this biocatalyst is regenerated; it can be used for many cycles of treatment. A system for conducting the continuous cyclic process of biocatalytic desulfurization of petroleum liquids is also disclosed.
