Abstract: Owing to the fact that the cracking C5 fractions would polymerize in the separation process, inhibitors need to be applied to minimize the polymerization. Hence, the recent progress in the application of inhibitors for cracking C5 fractions is reviewed. Based on the theory of free radical polymerization, the polymerization and inhibition mechanisms of cracking C5 fractions are discussed. The feature and functionality of different types of inhibitors in the separation process is mainly expounded. Finally, the future development of inhibitors for cracking C5 fractions is prospected.
