Abstract: Hydroprocessing of hydrocarbon charge stocks which contain sulfur and various metals is performed using two moving-bed reactors connected in series; intermittently fresh catalyst is added to and used catalyst is removed from the second reactor, the used catalyst is regenerated and charged to the first reactor for use in metals removal and initial hydrotreating of the charge stock.

Abstract: Crude oil petroleum derived from oil shale or tar sands and containing large amounts of highly abrasive particulate matter, such as rock dust or sulfated ash, is hydroprocessed in a dual function moving bed reactor which simultaneously removes particulate matter by the filter action of the catalyst bed. The effluent from the moving bed reactor is then separated and further hydroprocessed in fixed bed reactors with fresh hydrogen added to the heavier hydrocarbon fraction to promote desulfurization.

Abstract: A startup method for moving-bed reactors used in hydrocarbon conversion processes wherein the reactor is brought on-stream at full capacity while it contains less than a full loading of catalyst, and quantities of catalyst are intermittently added to the reactor while the hydrocarbons are being processed. Catalyst removal is then begun at a rate lower than the rate of catalyst addition and adjusted when the catalyst retention volume of the reactor becomes filled. The method is specifically adaptable to the hydrogenation of olefinic materials, the desulfurization of petroleum fractions and the production of liquid products from coal.

Abstract: A multiple-stage catalytic conversion system in which a hydrocarbonaceous charge stock and hydrogen flow serially through a plurality of catalytic reaction zones in each of which the catalyst particles are movable via gravity-flow. The reaction product effluent from each zone, in admixture with added hydrogen is heated prior to the introduction thereof into the succeeding reaction zone. The proportions of added hydrogen (portions of a recycled hydrogen-rich phase) are such that (i) vapor density decreases, and, (ii) lateral pressure drop across the catalyst bed increases in the direction of reactant stream flow through the plurality of reaction zones. The disclosed technique alleviates problems associated with the occurrence of stagnant catalyst areas as a result of catalyst particles being "pinned" within the reaction zone and thus unable to assume a downward gravity-flow pattern. In addition, the technique allows utilization of excess heater capacities before and between reaction zones.
