    摘要: A process for cracking hydrocarbon feedstock containing resid comprising: heating the feedstock, mixing the heated feedstock with a fluid and/or a primary dilution steam stream to form a mixture, flashing the mixture to form a vapor phase and a liquid phase which collect as bottoms and removing the liquid phase, separating and cracking the vapor phase, and cooling the product effluent, wherein the bottoms are maintained under conditions to effect at least partial visbreaking. The visbroken bottoms may be steam stripped to recover the visbroken molecules while avoiding entrainment of the bottoms liquid. An apparatus for carrying out the process is also provided.

    摘要: This invention relates to improvements in a process for the preparation of a magnetic catalyst, particularly a magnetic reforming catalyst. In such process, a Group VIII noble metal is incorporated within an inorganic oxide particulate mass, suitably by impregnation of preformed particles. The metal-containing inorganic oxide particulate mass, in the desired proportion, is then admixed with magnetic alloy particles, notably iron or cobalt, and an inorganic oxide precursor which serves as a binder, to form a particulate composite mass comprised of particles of magnetic alloy dispersed as inclusions within an inorganic oxide matrix.

    摘要: An adsorption process for the recovery of hydrogen from a feed gas or vapor which contains hydrogen in admixture with one or more hydrocarbon components, alone or in admixture with non-hydrocarbon components. Particulate adsorbent solids are provided with a magnetizable component, or components, and circulated between an adsorption zone in which hydrogen is concentrated in the off gas by contact of the adsorbent solids with the feed, and hydrogen recovered, and a desorption zone in which the exhausted solids are regenerated. Within the adsorption zone the feed is countercurrently contacted with the solids at relatively low temperature to selectively adsorb hydrocarbon, and perhaps other non-hydrogen components. The solids are formed into a moving, fluidized bed, and magnetically stabilized to suppress gross solids circulation while hydrocarbons are adsorbed from the feed. Occluded hydrogen is subsequently displaced from the particulate adsorbent solids with hydrocarbons, and the hydrocarbon enriched particulate adsorbent solids are then transported to the desorption zone. In the desorption zone the solids are fluidized, and the temperature of the bed is elevated sufficiently to desorb at least a portion of the hydrocarbons. The residual hydrocarbons are subsequently displaced by contact with stream in a magnetically stabilized bed of the solids. The wet solids are then dried by contact with hydrogen to displace the water, or steam, and then cooled to complete the regeneration.

    摘要: A noble metal-containing zeolitic catalyst having cracking activity and hydrogenation activity is pretreated by contacting the catalyst with a nitrogen-containing compound to decrease the cracking activity of the catalyst followed by treatment with hydrogen to recover the hydrogenation activity of the catalyst. The pretreated catalyst is used in a process for the hydrogenation of aromatic hydrocarbons.
