不同加氢改质催化剂对环烷基柴油改质的研究
|
摘要
以环烷基柴油为原料,分别采用轻油型、灵活型及中油型加氢改质催化剂进行加氢改质实验,研究不同加氢改质催化剂的差异性。实验结果表明,环烷基柴油加氢改质可生产高芳烃潜含量的重石脑油以及低温流动性能优异的改质柴油,当改质剂为轻油型改质剂时,需要的改质反应温度、反应氢耗最低;当改质剂为灵活型改质剂时,改质产物分布灵活性最佳;以中油型改质剂为改质段催化剂时,液体产品收率最高且改质柴油品质优异。
With naphthenic base diesel as feedstock,the differences between the light-oil type,flexible type and medium-oil type catalysts are studied through performing hydro-upgrading experiments. The results indicate that the hydro-upgrading catalysts can process naphthenic base diesel to produce heavy naphtha with high aromatic potential content and diesel with excellent low-temperature flow performance. The required hydro-upgrading reaction temperature and hydrogen consumption are the smallest when a light oil-type hydro-upgrading catalyst is used. The flexibility of product distribution shows the best when using the flexible type cracking catalyst.The liquid products yield exhibits the highest and the quality of products presents superior when using the medium oil type cracking catalyst.
