ABSTRACT:
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.
