利用HTC-200、DZG-10催化剂，以裂解C₅为原料，在小型固定床装置进行加氢实验。实验结果表明，裂解C₅经两段加氢后烯烃质量分数降至0.05%，经蒸汽裂解模拟评价，双烯收率达到45.44%。最后对加氢C₅进行了经济分析，就双烯收率而言，1 t加氢C₅与0.942 t乙烯原料油相当，表明加氢后的C₅是较理想的乙烯原料。

Hydrogenation experiments for C₅ fractions from steam cracker are carried out in a small fixed-bed by using HTC-200 and DZG-10 catalysts.Experimental results show that the content of olefins in C₅ fractions drops to 0.05% after two stages of hydrogenation.The total yield of ethylene and propylene reaches 45.44% through simulation evaluation in steam cracking process.Finally,the economic analysis on the hydrogenated C₅ fractions is carried out.As far as the total yield of ethylene and propylene is concerned,1 ton of hydrogenated C₅ is equivalent to 0.942 tons of feedstock oil,indicating that hydrogenated C₅ fractions is an ideal feedstock for ethylene.
