Macroparticle multihole PTFE which is made for a new hydrophobic catalyst supporter is prepared by dissolving the reagent for hole.

The key steps of hydrocracking of tetralin, the conversion of double ring compounds and the yields of mono-ring compounds were affected by the reaction temperature and the acidity of two catalysts.

CO hydrogenation catalyzed in heterogeneous system by supported bimetallic cluster has been studied in the light of the effect of reaction temperature, time and support.
