摘　　要：煤油中的硫化物能够腐蚀金属设备 ,造成环境污染 ,影响产品质量 ,因此对其脱硫技术的研究具有重要的现实意义 .生物催化法脱除石油产品中的硫是一种很有前途的油品脱硫方法 .本文研究在温和的条件下 ,利用适宜的微生物的代谢过程对煤油脱硫 .采用在煤油中加入不同浓度的硫醇后再加入一定量的微生物菌 ,利用分光光度计检测菌体数量增长情况 ,同时利用自动电位滴定法检测煤油中硫含量 。All fossil fuels contain organic sulfur compounds.The sulfides of kerosene can erode metallic equipment,polluted our environment and affect on products output.Desulfurization of these fuels is very important from the standpoint of the global environment.Biocatalytic desulfurization of petroleum products is a very promising approach.The purpose of this paper is to investigate the preliminary experiments of kerosene's desulfurization by using microorganism's metabolism under soft conditions.The cells were put into kerosene with different concentrations of mercaptan,and the growth of the bacteria was minitored by spectrophotoelectric analysis of spectrophotometer,and sulfur constant of kerosen was determined by auto\|potentiometric titration method.The results suggested that the strain was applicable to desulfurization.
