目前,中国有近40套MTBE生产装置,年产量达150万吨。中国生产的各类汽油中,催化裂化汽油占到80%左右。 从目前的加工手段看,提高辛烷值最根本的解决办法是发展催化重整,改变整个石油加工结构,但需要一个较长的过程,而且投资巨大。所以,通过添加MTBE提高辛烷值是目前提高中国汽油质量的最经济的手段。 译文: There are about 40-set plants for producing MTBE in china currently, its output reaches up to 1500kt/a. The gasoline output produced by catalytic cracking has held aboud 80% ofall-type gasoline. From viewpoint of the actual existent processing method, it is the most essential settlement for increasing the octane number to develop catalytic reforming (CR) and to change whole structure of oil processing, but these will need a longer course and the enormous investment. Therefore, increasing the octane number through adding MTBE to the gasoline is the most economic means for improving quality of domestic gasoline at present.
