由于原油质量和炼制加工水平的限制,我国炼油企业加工生产的汽油辛烷值普遍偏低一般来说炼油企业提高辛烷值的途径有三个:一是选择良好的原料和改进加工工艺,例如采用加氢裂化、催化重整等二次加工工艺。二是向产品中调入抗爆性优良的高辛烷值成分,例如异辛异丙苯、烷基苯等。三是加入抗爆剂。 Due to the limitation of crude oil quality and refining and processing level, the octane number of gasoline produced by the refining enterprises in our country is generally low. There are three ways to increase the octane number of the refining enterprises in general: First, select the good raw materials and improve the processing technology, for example Hydrocracking, catalytic reforming and other secondary processing technology. Second, the introduction of high antiknock into the product of high octane components, such as isooctyl benzene, alkyl benzene and so on. Third, join the antiknock agent.
