Hydrogenat ion of aromatic compounds in the middle distillate of Gudao crude oil was carried out with Pt/Al1O3 catalyst in a continuous flow fixed bed reactor system. The effect of temperature and LHSV on aromatic saturation was investigated at a constant pressure of 4.0 MPa and hydrogen-to-oil ratio 1000:1 and the kinetics were studied. A simplifying assumption was made of pseudo-first-order reversible self-inhibitive kinetics to treat all data obtained at chosen operating conditions. The proposed kinetic model...

The effect of temperature and LHSV on aromatic saturation was investigated at a constant pressure of 4.0 MPa and hydrogen-to-oil ratio 1000:1 and the kinetics were studied. A simplifying assumption was made of pseudo-first-order reversible self-inhibitive kinetics to treat all data obtained at chosen operating conditions. The proposed kinetic model gave a good agreement with experimental data. The optimal operating conditions for producing high density jet fuel from that distillate were established.

The second-stage hydrodesulfurization(HDS)catalyst for pyrolysis gasoline is strongly influenced by the method of preparation,the property of support,the dispersion and binding patterns of active components in the support,as well as the interaction between support and active components. The second-stage HDS catalyst LY-8602B for pyrolysis gasoline has successfully developed by using specific impregnation method.It is characterized by XRD,XPS and AAS,and its activity and stability are studied.The results show that the hydrogenation(HYD)and HDS activities of LY-8602B catalyst are better than those of the imported similar catalyst G-35B(Nissan Girdler Catalyst Co.Ltd.).The LY-8602B catalyst is now in successful commercial use in the pyrolysis gasoline HDS unit of the 300, 000 t/a ethylene cracker in Yangzi Chemical Industry Company to displace the imported catalyst.
