1A New Kinetic Model for Residue Hydrotreating Based on Chemical Reaction Sections显示文摘New definition of virtual molecular-group components about CH and CH2 is proposed in the paper.The new reaction,hydrogenation of CH to CH2(HDCH),can be used to represent the change of C and H in RHT.By using the lumping approach,the kinetic models about HDCH,HDS,HDN,HDCCR,HDM,HDNi and HDV reactions were established.They are key components of the new kinetic model for RHT based on reaction sections.During the construction of kinetic model,goodness-to-fit(R^2)between test data and model data was set as the target value,and the model parameters were calculated accurately.In verification test,the predicted content of H,S,N,CCR,M,Ni and V can match well with the test data.Zhang Kui Dai Lishun Nie Hong Shao Zhicai Liu Tao Deng Zhonghuo Han Wei Jia Yanzi 2020China Petroleum Processing & Petrochemical Technology2020,22,2:4
2Study on the Effect of Catalyst Properties on Residue Hydroconversion显示文摘The effect of catalyst properties on residue oil hydroconversion was studied at moderate operating conditions(at a temperature of 400 ℃, an initial hydrogen pressure of 10 MPa, and a reaction time of 4 h) in a batch mode slurry phase with different catalyst samples. The results showed that the catalyst acidity had a good effect on residue conversion and MCR(micro carbon residue) conversion but brought about higher coke yield. Residue conversion was thermally induced but the catalyst acidity changed its conversion route. A catalyst with higher metal loading, higher hydrogenation activity and appropriate pore size had higher sulfur and metal removal rate, higher MCR conversion and also a lower coke formation. The activity of spent commercial catalyst AS1 and DS1 was slightly lower than the corresponding fresh ones but was still high enough for residue oil hydroconversion. It assumes that the role of the catalyst is to activate hydrogen species toward reaction with an aromatic carbon radical to yield a cyclohexadienyl type intermediate which will turn into liquid and also to absorb the mesophase which can easily aggregate to form coke.Tong Fengya Yang Qinghe Li Dadong Dai Lishun Deng Zhonghuo 2016China Petroleum Processing & Petrochemical Technology2016,18,1:1

5Effects of Hydrotreating Severity on Hydrocarbon Compositions and Deep Catalytic Cracking Product Yields显示文摘Residue deep hydrotreating(RDHT)process was developed by the Research Institute of Petroleum Processing(RIPP)to provide high quality feedstock for deep catalytic cracking(DCC)process.In this research work,the effects of RDHT process and reaction severity on heteroatom removal,hydrogen content increase,hydrocarbon composition improvement,and DCC product yields were studied.It was showed that the RDHT process can effectively reduce heteroatoms,increase hydrogen content and improve the hydrocarbon compositions,which can contribute to an increase of light olefins yield in DCC unit.Deng Zhonghuo Dai Lishun Niu Chuanfeng Jia Yanzi Wei Xiaoli Cai Xinheng 2021China Petroleum Processing & Petrochemical Technology2021,23,3:1
6Residue Upgrading in Slurry Phase over Ultra-fine NiMo/γ-Al_2O_3 Catalyst显示文摘In this article, residual oil hydroconversion was studied in slurry phase in the presence of fine solid Ni Mo/γ-Al2O3 catalyst and the effects of operating conditions were carefully studied. The results showed that residue conversion was only affected by the reaction temperature and reaction time. The coke yield increased with a higher reaction temperature, a bigger catalyst particle size, a longer reaction time, a lower initial hydrogen pressure and a lower catalyst concentration. Heteroatoms removal rate increased with a higher reaction temperature, a longer reaction time, a higher initial hydrogen pressure, a higher catalyst concentration, and a smaller catalyst particle size. The role of catalyst in the slurry bed technology was discussed and its function could be stated as follows: the metal was applied to activate the hydrogen atoms for removing heteroatoms and saturating aromatics, while the support of the catalyst was used to prevent the mesophase coalescence for reducing coke formation.Tong Fengya Yang Qinghe Li Dadong Dai Lishun Deng Zhonghuo 2015China Petroleum Processing & Petrochemical Technology2015,17,3:0
