摘要: Abstract In the preparation of sulfated zirconia catalysts (SZ) by controlled impregnation technique, properties products, including catalytic activity, are influenced precursor from which Zr(OH)4 is obtained, pH its precipitation, and temperature time calcination after sulfation. The best catalyst for isomerization methylcyclopentane (MCP) to cyclohexane was obtained zirconium oxynitrate as precursor, with precipitation conducted at a constant 7 in air, sulfation previously described, 610°C 5 h. nature chemical process occurring during discussed light results obtained.
