Abstract
In the synthesis of hydrocarbons and oxygenated derivatives from carbon monoxide and hydrogen using a bed of fluidized iron catalyst, a quantity of powdered inert material having a particle size larger than that of the catalyst is admixed therewith, the particle sizes being such that good fluidization is obtained while there is substantially no relative movement of the bodies of inert material and catalyst as a whole. The inert material may be silica gel, dolomite, sharp sand or alumina, and is preferably of lower density than the catalyst. The amount added should be such that a major portion of the mixture has an average particle size above 40 microns. An iron catalyst which after use and particle breakdown is 55.5 per cent 0-20 microns is mixed with sufficient silica gel having 4 per cent 0-20 microns to give a product which is 25 per cent of this size. Reaction conditions are about 600-750 DEG F., 300-800 pounds per square inch, and gas inlet velocity of 0.1-1.5 feet per second.ALSO:In the synthesis of hydrocarbons and oxygenated derivatives from carbon monoxide and hydrogen using a bed of fluidized iron catalyst, a quantity of powdered inert material having a particle size larger than that of the catalyst is admixed therewith, the particle sizes being such that good fluidization is obtained while there is substantially no relative movement of the bodies of inert material and catalyst as a whole.
