分散型镍、铁催化剂用于重油-煤的加氢共炼研究
Study on dispersed Ni and Fe catalysts for coal-heavy oil co-processing
摘要
Abstract
The dispersed nickel or ferric sulfide catalyst were prepared from nickel or ferric nitrate by dissolving in H2O, methanol or N-N dimethyl foramide ( DMF) and then dispersing in heavy oil and presulfurizing with sulfur at 330 t. The results show that the particles sizes of the nickel and ferric sulfides from organic-soluble catalysts precursors are smaller and more symmetrical than those of the traditional water solution. The particles sizes of nickel and ferric sulfides from DMF-solu-ble catalysts precursors are about 10-40 nm and 30-50 tun, exhibiting the advantage of DMF on methanol for the corresponding particles size from methanol-soluble respectively about 50 nm and 120 nm, which resulted from the lower viscosity and good compatibility of the preparing system. In the two heavy oils ( LGAR,Du-84) and two coals(Shenhua bitumite or Neimeng brown coal) co-processing system at 420 X., 1 h, 8.0 Mpa H2(cold) and the mass ratio of coal to oil 1 =3, the catalysts prepared from the organic solution could greatly improve the co-processing effect compared with the catalysts prepared from the water solution. XRD analysis shows that the aggregation and deactivity of the organic-soluble nickel and ferric catalysts are slower than that of corresponding water-soluble catalysts, especially with the DMF-soluble catalysts.关键词
