NiW/γ-Al2O3催化剂的低温煤焦油加氢性能研究
Hydroprocessing of low temperature coal tar on NiW/γ-Al2O3catalyst
摘要
Abstract
γ-Al2O3 supported catalysts with different Ni/W atomic ratios for the hydroprocessing of low temperature coal tar (LTCT) were prepared and characterized by BET, XRD, H2-TPR and TG analysis. The hydroprocessing of <350' ℃ fraction of LTCT was carried out in a fixed-bed reactor. The product distribution and composition were analyzed by distillation, GC/MS, fluorescent indicator adsorption and elementary analysis. The results show that NiO and WO3 are evenly distributed on the support surface; and low-loading NiO is difficult to reduce since the strong force is formed with the support surface. The phenol conversion, the selectivity of kerosene fraction and the content of naphthene and hydro-aromatic in the product are the highest at a Ni/W atomic ratio of 0. 38, while the activities of HDS and HDN and the H/C atomic ratio in the product are also the best. It indicates that the NiW/7-Al2O3 catalyst with an optimum Ni/W atomic ratio of 0. 38 is appropriate for the hydroprocessing of LTCT.关键词
