摘要： The present invention provides a process for hydro-demetallizing of residual hydro-carbonaceous feedstock. The process includes passing the feedstock to a vertically-disposed reaction zone to produce an effluent which is passed to at least one fixed bed reactor for further processing. The reaction zone includes at least one moving bed reactor, having at least one catalyst bed of hydro-demetallization catalyst configured for catalyst addition and removal. The hydrodemetallization catalyst is subjected to in-line fresh catalyst deairing, pressurizing, and hydrocarbon soaking via a catalyst sluicing system and sulphidic activation before entering the moving bed reactor at a top portion of the moving bed reactor. The hydrodemetallization catalyst is added to the moving bed reactor through gravity and any spent hydrodemetallization catalyst is removed from a bottom portion of the moving bed reactor. The removed spent hydrodemetallization catalyst is subjected to in-line spent catalyst hydrocarbon removal, depressurizing, inerting, and airing.

摘要： The invention provides a process for preparing a hydrowax comprising the steps of: (a) providing a hydrocarbonaceous feedstock which contains more than 4% by weight of hydrocarbons boiling in the range of from 550 to 800° C.; (b) hydrotreating the hydrocarbonaceous feedstock with a hydrotreating catalyst in the presence of a hydrogen-containing gas under hydrotreating conditions to obtain a hydrotreated product; (c) hydrocracking at least part of the hydrotreated product as obtained in step (b) with a hydrocracking catalyst in the presence of a hydrogen-containing gas under hydrocracking conditions to obtain a hydrocracked product, which hydrocracking catalyst contains a zeolitic component which is present in an amount of at least 14 wt %, based on the total weight of the hydrocracking catalyst, and wherein the volume ratio of the hydrotreating catalyst as used in step (b) and the hydrocracking catalyst is more than 1; and (d) recovering from the hydrocracked product as obtained in step (c) the hydrowax.
