柠檬酸对 WP 催化剂噻吩加氢脱硫性能影响
Effect of Citric Acid on Hydrodesulfurization Activities of T hiophene for Tungsten Phosphide Catalysts
摘要
Abstract
Citric acid(CA) as additive ,WP catalysts with different molar ratio for citric acid(CA) to WP were prepared by in-impregnation and temperature programmed reduction(TPR) method .The catalysts were characterized by X-diffraction(XRD) , BET surface area , scanning electron microscope (SEM ) and thermal gravimetric/differential thermal (TG ) methods . The thiophene hydrodesulfurization(HDS) activities of WP catalysts were evaluated through a micro-high press reactor .The results indicate that WP bulk structure is not changed by addition of CA ,while the WP crystal particle growth is inhibited and the BET surface area is improved .It is possible that the process of nitrate radical decomposition is moved and the initial temperature and end temperature is deduced by addition of CA and resulting in the active species of WP is well dispersed to the catalysts surface . Catalyst with CA possessed higher thiophene HDS activities .The Cat-5 catalyst show the highest HDS activity and it gave HDS conversion of 20 .4% higher than that without CA .关键词
