查询词典 naphthalene

It was found that indene and naphthalene, which have harmful effects on the combustion property, were produced because of the hydrogen transfer reaction at high temperatures. High conversion ratio and low content of aromatics could not be obtained simultaneously.

在较高温度时，由于氢转移反应，产物中出现了茚、萘等低氢碳比化合物，会影响燃料的燃烧性能，应用时需要根据性能要求在高裂解转化率与低芳烃收率之间进行权衡。
