摘要
考察了含有不同分子筛的催化剂对重整生成油脱烯烃反应的催化性能。催化剂评价实验结果表明,分子筛的孔结构、催化剂酸性以及原料中的重组分对催化剂的脱烯烃性能有较大影响。与白土相比,含有适量改性REY分子筛的催化剂具有较好的脱烯烃活性、稳定性和再生性能。
The performance of various molecular sieve catalysts on the removal of trace olefins from reformate was investigated. Results of catalyst evaluation show that the pore structure of molecular sieve, acidity of catalyst and heavy components in reformate have great influence on removing trace ole-fins from reformate. Compared with clay, catalyst containing a suitable amount of modified REY molec-ular sieve exhibits good activity, stability and regeneration property.
