چکیده
|
Como-supported micro/mesoporous catalysts (como/hzsm5(x)-hms) were synthesized by varying the weight percent of zeolite (10, 20, 30 and 40 wt%). catalytic functionalities were investigated for hydrodesulphurization reaction of dibenzothiophene over a wide temperature range of 250–400 °c. characterization methods as xrd, xrf, ft-ir, uv–vis drs, nh3-tpd, h2-chemisorption, nitrogen adsorption–desorption and tga confirmed the obtained results from these catalysts. a significant enhancement of the catalytic activity was observed for the catalysts supported on como/hzsm5(20)-hms at t = 350 °c (>97%).
