Analysis of fouling mechanisms of ceramic membranes in microfiltration of Raney nickel catalysts suspension;

The studies on production of pure cyclopentadiene by depolymerization-rectify of technical dicyclopentadiene and the influenceable factors about preparation of cyclopentene by liquid hydrogenation of cyclopentadiene at the Raney Nickel catalyst were carried out.

Preparation of methyl isobutyl carbinol(MIBC)was studied by catalytic hydrogenation of methyl isobutyl ketone(MIBK)in liquid phase on Raney nickel catalyst.

A kind of highly active skeletal Ni catalyst was prepared from amorphous NiAl alloy ribbon by NaOH activation after grinding.
