    摘要： Apparatus for the treatment of a liquid hydrocarbon charge containing solids or solids-forming contaminants, e.g., inorganic solids, metals and asphaltenes, which includes a contactor vessel having a liquid charge inlet, a vaporizing media inlet above the charge inlet and a vapor-solids outlet. An atomizer is positioned in the charge inlet for forming small particles of the liquid charge and directing the particles of liquid in a substantially horizontal flat pattern into the contactor vessel. A premix downcomer having a dispersion grid positioned therein is located in the vaporizing media inlet for introducing a fluidized mixture of a gas dispersion media and hot circulating solid particles into the contactor vessel in a substantially vertical flat pattern to traverse the path of the liquid particles and intimately contact the liquid particles. The vapor-solids-outlet is positioned in the contactor vessel substantially opposite the liquid charge inlet to receive product vapors and entrain solid particles and rapidly pass the same into cyclones connected to the vapor-solids-outlet for separating solid particles from product vapors. A stripper vessel is located beneath the contactor vessel for receiving heavy solid particles and stripping hydrocarbons therefrom.

    摘要： A continuous fluidized process for upgrading a heavy liquid hydrocarbon charge-stock containing solid or solid-forming contaminants, e.g., inorganic solids, metals and asphaltenes. The charge is atomized to provide a stream of liquid particles introduced horizontally into a horizontal contacting zone to contact a vertical curtain of fluidized hot solid particles so as to vaporize hydrocarbons in the charge without substantial cracking, the solid particles being solely derived from the contaminants in the charge. The mixture of hydrocarbon vapors and solid particles are rapidly separated, carbon is burned from the separated particles, and the resulting hot solid particles are recycled to the contacting zone. The hydrocarbon vapors are condensed and there is recovered a liquid product having a substantially reduced content of contaminants.

    摘要： Whole crude and bottoms fractions from distillation of petroleum are upgraded by high temperature, short time contact with a fluidizable solid of essentially inert character to deposit high boiling components of the charge on the solid whereby Conradson Carbon values, salt content and metal content are reduced. The upgraded hydrocarbon fraction may be supplied to fractionator, in which case the high temperatue contactor serves as a heater, e.g. crude heater for crude distillation, in addition to improving quality of the fractions derived by distillation. For charge stocks boiling above about 500.degree.-650.degree. F., the upgrading process yields a product suitable for charge to catalytic cracking in that Conradson Carbon, salts and metals are reduced to levels tolerable in catalytic cracking.

    摘要： A PROCESS FOR THE SEPARATION OF AROMATIC HYDROCARBONS WHICH PROCESS COMPRISES THE ADSORPTION OF SELECTED FEED COMPONENTS FOLLOWED BY DESORPTION OF SELECTED FEED COMPONENTS FROM A SOLID ADSORBENT THROUGH THE USE OF A DESORBENT MATERIAL. THE PROCESS ALLOWS THE ADSORBENT WHICH HAS JUST CONTACTED FEED STOCK AND WHICH SELECTIVELY ADSORBS A SELECTED COMPONENT THEREFROM TO BE CONTACTED WITH A QUANTITY OF SELECTIVELY ADSORBED FEED COMPONENT TO REMOVE UNDESIRED RAFFINATE COMPONENTS WHICH ARE EITHER ADSORBED BY THE ADSORBENT OR PRESENT WITHIN THE INTERSTITIAL VOID SPACES BETWEEN THE ADSORBENT PARTICLES PRIOR TO RECOVERY OF THE EXTRAT MATERIAL IN A DESORPTION STEP. THE SELECTIVELY ADSORBED FEED COMPONENT CAN BE TAKEN FROM EITHER A PRODUCT EXTRACT STREAM OR DIRECTLY FROM THE PORTION OF THE ADSORBENT IN WHICH THE DESORPTION STEP TAKES PLACE.
