| 摘 要： | 采用假单胞菌(Pseudomonas delafieldii)菌株R-8和红色红球菌(Rhodococcus erythropolis)菌株N1-36研究了加氢精制柴油脱硫工艺，两株菌脱除柴油中有机硫的活性相近. 添加表面活性剂能提高菌株对柴油的脱硫率；当Tween80存在、搅拌转速为250 r/min时，菌株R-8最高可脱除硫含量<300 mg/L的柴油中72%的有机硫；但当硫含量超过1000 mg/L时，微生物脱硫率极低. |

| Abstract: | The pseudomonas delafieldii strain R-8 and Rhodococcus erythropolis N1-36 were used to remove the sulfur from hydrogenated diesel oil. Both strains utilize the organic sulfur compounds from diesel oils with approximate activities. Surfactants can increase the desulfurization rate. When agitating rate was 250 r/min with Tween80 present, the strain can remove 72% of the organic sulfur from low sulfur diesel oil (S<300 mg/L) in 72 h. But when sulfur concentration was higher than 1000 mg/L, the sulfur removal rate of diesel oil by strain R-8 is very low. |
| Keywords: | diesel oil biodesulfurization of organic sulfur surfactant |
