Abstract: With the continuous optimization of China's refining process and gasoline pool composition, the conversion of C4 olefins into clean gasoline with high octane number by oligomerization reaction has been developed rapidly, with solid acid as most widely used catalyst. The source of raw materials and processing route of olefins were briefly introduced with the applications of various kinds of solid acid catalysts being summarized in this paper, mainly including solid phosphoric acid, acid resin, zeolite, clay, heteropoly acid, sulfonated metal oxide and metal/acid supported catalysts, etc. The mechanism of carbon ion reaction over solid acid catalyst was also summarized. It was found that among these catalysts, zeolites has the advantages of adjustable pore and acidity, easy regeneration, no pollution and high activity, which have more industrial application potentials in the future.

Key words: solid acid catalyst, light olefins oligomerization, carbonium ion mechanism, zeolites
