摘要: Abstract Mild hydrocracking composite catalysts based on NiMo/γ-Al2O3-Beta zeolite have been prepared and the influence of location NiMo phases has studied. A good activity highest HDS conversion was found during a vacuum gasoil with catalyst where is located alumina component then mixed in proportion 1 : by weight. The crystal size beta had significative catalytic behaviour, being better smaller crystallite is. small beta-based displayed higher than conventional USY silica-alumina-based catalysts, giving selectivity towards middle distillates.
