Abstract

A series of Ti-incorporated bulk Ni2P catalysts was prepared by means of temperature-programmed reduction, and the role of metallic Ti on the structure and catalytic activity of the Ni2P catalysts was studied. For this purpose, bulk Ni2P catalysts with metal Ti contents of 0.005 wt%, 0.01 wt%, and 0.02 wt% were synthesized. X-ray diffraction, CO uptake, Brunauer–Emmett–Teller measurements, and X-ray photoelectron spectroscopy were utilized to characterize the catalysts. Addition of titanium could increase the surface area and promote the formation of small, highly dispersed Ni2P particles. The Ti0.02-Ni2P system with a Ti molar fraction of 0.02 showed the highest hydrodesulfurization activity of 99.6%, which was an increase of 44% compared with that found for the bulk Ni2P.

钛对二苯并噻吩在Ni2P上加氢脱硫性能的影响

采用程序升温还原法制备了Ti掺杂Ni2P本体催化剂，研究了金属Ti对Ni2P催化剂结构和催化活性的影响。为此，合成了金属Ti含量分别为0.005 wt%、0.01 wt%和0.02 wt%的大块Ni2P催化剂。利用x射线衍射、CO吸收、brunauer - emmet - teller测量和x射线光电子能谱对催化剂进行了表征。钛的加入增加了表面面积，促进了小的、高度分散的Ni2P颗粒的形成。Ti摩尔分数为0.02时，Ti0.02-Ni2P体系的加氢脱硫活性最高，达到99.6%，比本体Ni2P体系的加氢脱硫活性提高44%。
