The invention relates to a process of catalytic hydrovisbreaking of a hydrocarbon charge comprising the following stages:

Catalytic composition comprising a metal sulfide suspended in a liquid

A hydrotreatment method, for example, hydroviscoreduction or hydrodesulfurization in which the charge of hydrocarbons is reacted with hydrogen in contact with a catalyst finely dispersed in the liquid phase. To separate the product from the catalyst, the effluent freed from its accompanying free gas is passed along, and in contact with the upstream wall of a porous inorganic membrane. The oil that has not been filtered contains a concentrate of catalyst and is recycled to the hydrotreatment reactor. The filtered oil constitutes the product of the method.

Method for the liquid phase hydrotreatment of heavy hydrocarbons in the

The invention relates to a process for catalytic treatment of heavy hydrocarbons, in a fixed or moving bed, over a catalyst containing an alumina carrier and at least one catalytic metal or compound of metal from groups VB, VI B and VIII of the periodic classification of elements, characterized by the direct injection into the charge, continuously or periodically, of at least one metal compound selected from the group consisting of halides, oxyhalides, oxides, polyacids and polyacid salts of metals from groups VI B, VII B and VIII, before introducing the charge into the hydrotreatment zone.

Process for catalytic hydrotreatment of heavy hydrocarbons, in fixed or

The hydroconversion of a heavy hydrocarbon charge containing asphaltenes and metal, sulfur and nitrogen impurities is performed in the presence of a catalyst comprising:

Process for the catalytic hydroconversion of heavy hydrocarbons in

Thermostable, infusible and insoluble polymer obtained by thermosetting aromatic oligomers of low molecular weight in the presence of an acid catalyst, said aromatic oligomers having an average molecular weight up to about 5000, a softening temperature from 80.degree. to 400.degree. C. and being obtained by separation from the reaction mixture produced by reacting meta-terphenyl with acetyl chloride and aluminum chloride.
