乙烯选择性
1.
The effects of zeolite structure, silica alumina ratio, reaction temperature and con-version on ethylene selectivity in catalytic cracking reaction were studied.
通过对不同结构及硅铝比的分子筛进行催化裂化反应中低温低转化率、高温高转化率裂解的反应以及反应温度对乙烯选择性影响的考察,认为:分子筛的孔径是影响乙烯选择性的主要因素,中小孔分子筛对乙烯的选择性都比大孔分子筛的好。

乙烯收率
1.
Ethylene yields in cases of naphtha crack- ing,naphtha and ethane co-cracking and ethane cracking in millisecond furnace are compared with each other.
60及注硫条件下的单独裂解为优,乙烯收率达到40。
2.
In the process of ethylene production,ethylene yield cannot be measured on-line via traditional approaches.
针对乙烯生产过程中,用传统方法难以直接完成对乙烯收率的在线测量的问题,提出了一种新型差分进化粒子群混合优化算法,建立了乙烯收率软测量建模。
