摘要
Abstract
The mass concentration of water in kerosene has a significant effect on the growth of microorganisms which harm aircrafts seriously. The higher water mass concentration, the more microorganisms, so the more seriously aircrafts are harmed. Compared with the conventional anti-microbial chemical additives, silica gel and four types of molecular sieve 3A, 4A, 5A, 13X were taken as adsorbents in a series of static adsorption experiments to remove water contained in kerosene. The results show that the best conditions for removing water in kerosene are as follows; 3A molecular sieve as adsorbent, the adsorption time of 180 min, the adsorbent dosage of 2 g in 100 mL aviation kerosene, the grain diameter of 80 mesh. Under these conditions, the water contained in kerosene can be reduced from 1.2 × 10 -4 mg/L to 8 × 10 -6 mg/L. And the content of microorganisms can be reduced from 1 000 piece/mL to 5 piece/mL or to aseptic condition when using the content of microorganisms as the indicator.关键词
