    Abstract: A slurry phase reactor is designed to treat extra heavy petroleum crude in a combination of thermal-zone and catalytic-zone in a counterflow system where liquid feed is added to the top and hydrogen at the bottom. Feed enters the gas-phase thermal zone, where it passes to a liquid-phase thermal zone. In the liquid-phase thermal zone, the hydrocarbon is thermally cracked and the unreacted liquid is further passed to a catalytic-zone below in communication with the thermal-zone. Catalyst can be added or removed as required in a continuous mode without shutting down the system. The heat generated inside the catalytic cracking zone is distributed to the entire reactor as the gaseous product flows upward. Feed is brought to the reaction conditions by the heat recovered from the gas-phase zone. Reaction temperature could be controlled by feed temperature.

    Abstract: A liquid phase catalytic hydrogenation process is described in which an organic feedstock, such as an aldehyde containing from 2 to about 20 carbon atoms, is contracted with hydrogen in the presence of a solid hydrogenation catalyst under hydrogenation conditions to produce a hydrogenation product, such as the corresponding alcohol containing from 2 to about 20 carbon atoms, which process comprises passing a feed solution of the organic feedstock in an inert diluent therefor downwardly in co-current with a hydrogen-containing gas through a hydrogenation zone containing a bed of a particulate hydrogenation catalyst whose particles substantially all lie in the range of from about 1.5 mm to about 5 mm, maintaining the bed of catalyst particles under temperature and pressure conditions conducive to hydrogenation, recovering from a bottom part of the bed a liquid phase containing the hydrogenation product, controlling the rate of supply of the feed solution to the bed so as to maintain a superficial liquid velocity of the liquid down the bed in the range of from about 1.5 cm/sec to about 5 cm/sec, and controlling the rate of supply of the hydrogen-containing gas to the bed so as to maintain at the top surface of the bed of catalyst particles a flow of hydrogen-containing gas containing from 1.00 to about 1.15 times the stoichiometric quantity of hydrogen theoretically necessary to convert the organic feedstock completely to the hydrogenation product.

    Abstract: Method for the treatment of fluidized carbon black with gases in a fluidized bed, wherein the carbon black and the treatment gases are conveyed for introduction in an unique operating procedure into the treating region in a countercurrent stream manner. The mass streams of the carbon black and the treating gases are held constant and the mass streams of the starting carbon black or the treated carbon black is regulated with the help of an optical electrical level sensor so that the height of the fluidized bed is held on a predetermined level. An apparatus is shown for the carrying out of the fluidized bed countercurrent process which has a novel carbon black product delivery system and is provided with a optical electrical level sensor means for controlling the level of the fluidized bed. The sensor comprises a hair pin shaped lighting circuit composed of two legs or rods separated by a gap. A light source impinges on the end of one of the said legs and the other leg is oriented to an electrical signal generating light sensor.

    Abstract: A continuous process and system is provided for a petroleum oil in a multi-phase fixed bed catalytic reactor column comprising methods and means for:feeding the oil and a reactant gas at production flow rates above a first bed of porous solid catalyst particles under conversion conditions for cocurrent downward flow therethrough, collecting and withdrawing the treated oil from the first bed and redistributing at least a portion of the treated oil to at least one succeeding catalyst bed while permitting the gaseous phase to flow directly to the succeeding lower catalyst bed, recycling a quantity of treated oil collected below a catalyst bed and reapplying the treated oil at a preceding redistribution zone above the bed from which treated oil is collected, whereby the total of oil production flow rate and recycled treated oil flow rate is maintained at a predetermined minimum sufficient to effect uniform catalyst wetting. This technique is useful for hydrodewaxing of oils over zeolite catalysts.
