  • Process for the production of hydrogen by catalytic reforming of methanol with water vapor
    Patent number: 4840783
    Abstract: The invention relates to a process for the production of hydrogen by catalytic reforming of methanol with water vapor. A mixture of methanol, water and carbon dioxide is passed in contact with a catalyst, containing copper, in a fixed bed, in a catalytic zone, at a temperature comprised between 150.degree. and 400.degree. C., the molar ratio of the carbon dioxide to the methanol, at the entrance of the catalytic zone, being comprised between 0.001 and 0.2.

  • Process for hydrotreating heavy hydrocarbons in liquid phase in the presence of a dispersed catalyst
    Patent number: 4285804
    Abstract: A mixture of heavy hydrocarbons, hydrogen and fresh catalyst comprising metals from the groups Vb, VIb, VIIb or VIII is passed first in a furnace for a limited heating time and then in a reactor where recycled catalyst is also added; the recycled catalyst is used in the form of a suspension recovered by fractionation of the reaction product.
