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計算油品的烯烴百分含量的方法。
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. 結果表明噻吩能有效抑制輕柴油的結焦，并可促進輕柴油裂解，提高烯烴收率。
