The sorption process involves combining a simulated countercurrent flow system with a stationary magnetically stabilized fluidized bed to achieve continuous adsorption-desorption to separate components of a feedstream.

Continuous sorption process

A process is described using novel thallium-promoted iron catalysts in CO hydrogenation with steam. Mixtures of CO and steam are converted to liquid C.sub.6 -C.sub.13 hydrocarbons containing substantial amounts of C.sub.6 -C.sub.13 aromatics.

An endothermic or exothermic chemical reaction may be conducted whereby a flowable bed of magnetizable particles such as catalytic particles is subjected to an applied magnetic field, a reaction fluid is circulated through the bed under conditions so as to effect an exothermic or endothermic reaction, the bed of particles is circulated at a rate such that the temperature profile of the bed and reaction fluid throughout their entire contact in a reactor is at or about the temperature profile which results in maximization, at each point along the reactor, of at least one of: conversion, selectivity or product yield, and the desired reaction product is recovered. In a preferred embodiment the solids are transported countercurrently to the reaction fluid in the synthesis of ammonia. In another preferred embodiment the solids are transported cocurrently with the reaction fluid in the synthesis of ethylene oxide.

CO hydrogenation process is described utilizing novel thallium-promoted iron catalysts. Mixtures of CO/H.sub.2 are selectively converted to liquid C.sub.6 -C.sub.11 hydrocarbons containing C.sub.6 -C.sub.11 aromatics, alpha olefins and very small amounts of C.sub.23 + hydrocarbon waxes.

Process using iron-thallium catalysts in CO hydrogenation

CO hydrogenation process for producing alcohols is described utilizing novel thallium-promoted iron catalysts. Mixtures of CO/H.sub.2 are selectively converted to liquid C.sub.6 -C.sub.12 hydrocarbons containing C.sub.6 -C.sub.12 alcohols with attendant low methane and low CO.sub.2 make.

Process for producing alcohols using iron-thallium catalysts

A solvent extraction process for tar sands is disclosed wherein a low boiling solvent having a normal boiling point of from 20.degree. to 70.degree. C. is used to extract tar sands. The solvent is mixed with tar sands in a dissolution zone, the solvent:bitumen weight ratio being maintained at from about 0.5:1 to 2:1. This mixture is passed to a separation zone in which bitumen and inorganic fines are separated from extracted sand, the separation zone containing a classifier and countercurrent extraction column. The extracted sand is introduced into a first fluid-bed drying zone fluidized by heated solvent vapors, so as to remove unbound solvent from extracted sand while at the same time lowering the water content of the sand to less than about 2 wt. %. The so-treated sand is then passed into a second fluid-bed drying zone fluidized by a heated inert gas to remove bound solvent. Recovered solvent is recycled to the dissolution zone.
