fresh catalyst

The adsorption site strength of ammonia, oxygen and propylene in the fresh catalyst is weaker, and the adsorption site density is greater, so its catalytic activity is better.

新鲜催化剂对NH3、O2和丙烯的吸附强度较弱，但吸附中心密度较大，因此性能较好；

After raising the activity of the equilibrium catalyst with higher fresh catalyst makeup, the total liquid yield and the slurry yield maintained unchanged with the feedstock blending 40% AR and 40% VR.

增加新鲜催化剂补充率提高平衡催化剂活性后，当原料中掺炼40%常压渣油和40%减压渣油时，总液体收率和油浆产率基本不变。

SEM, TEM, FT-IR and TG have done the characterizations of fresh catalyst, deactivated and non-deactivated reacted catalyst.

本文利用SEM、TEM、FT-IR和TG等基本表征手段对新鲜催化剂和典型的苯丙烯烷基化反应失活和未失活的催化剂进行了表征。

The reaction mechanism for hydrogenation of 1-hexene with the catalyst ( II) was concluded by comparing the FT-IR and XPS spectra of the fresh catalyst and after it was run for 9 times.

通过对催化剂使用前后XPS及红外谱图进行分析，推测出该固相化催化剂催化1-己烯加氢反应的反应机理。
