The average molecular weight and bromine number were used to calculate weightpercent of olefine in petroleum products. 本文提出了由油品平均分子量和溴值计算油品的烯烃百分含量的方法。
The results show that thiophene can inhibit effectively the coking of light gas oil in promoting pyrolysis of light gas oil and increase the olefine yields. 结果表明噻吩能有效抑制轻柴油的结焦，并可促进轻柴油裂解，提高烯烃收率。
