| abstract |
A hydrotreatment process, for example hydrofiscoreduction or hydrosulfurization, in which a hydrocarbon feedstock 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 the accompanying free gas, is passed into contact with the upstream wall of an inorganic porous membrane. The oil which has not filtered contains a catalyst concentrate and is recycled to the hydrotreatment reactor. Filtered oil is the product of the process. (CF DRAWING IN BOPI) |
