<p>PURPOSE:To convert a heavy hydrocarbon oil into a hydrocarbon oil having high value added, by using as a hydrogenation catalyst for the heavy hydrocarbon oil, a composite material made of a clay mineral containing as a main constituent magnesium silicates, a specified pseudoboehmite, and a metallic component. CONSTITUTION:The catalytic hydrogenation catalyst for heavy hydrocarbon oils is made up of a clay mineral having a double-chain structure and containing magnesium silicates as main constituents, a pseudoboehmite that has, in a CuKalpha line powder X-ray diffraction spectrum, a half width valve at the peak of a (020) face in the range of about 0.8 deg.-4 deg. and a peak intensity thereof in the range of about 1.2-8 times the intensity at 2theta=10 deg., and a metallic component of Groups VB, VIB, etc. of the Periodic Table. When this catalyst is used objectionable matters such as asphaltene or heavy metals contained in the raw material can be reduced, and the raw material can be converted into a hydrocarbon oil having high value added.</p> |
