Abstract
Three phase reactions are carried out in a slurry bubble column, e.g., hydrocarbon synthesis, wherein rising gas bubbles fluidize a catalytically active solid dispersed in a liquid phase and in the presence of at least one other solid different chemically or physically from the catalytically active solid.
Claims21
A slurry phase hydrocarbon synthesis process for the conversion of hydrogen and carbon monoxide at reaction conditions to products which comprises
- injecting a gas comprising hydrogen and carbon monoxide at or near the bottom of a bubble column containing a slurry liquid, a catalytically active first solid and at less a second solid, dispersing the solids in the slurry liquid, all of the energy therefor being supplied by the gas, in the absence of liquid product recycle, the amount of the second solid being sufficient to increase the bed height of the first catalytic solid by at least 10%, and
- recovering liquid product.
A slurry phase hydrocarbon synthesis process for the conversion of hydrogen and carbon monoxide, at reaction conditions, to liquid products which comprises
- injecting a gas comprising hydrogen and carbon monoxide at or near the bottom of a bubble column reactor containing a slurry liquid, a catalytically active first solid comprising cobalt or ruthenium and at lest a second solid, dispersing the solids in the slurry liquid, all of the energy therefor being supplied by the gas, and in the absence of liquid product recycle, the amount of the second solid being sufficient to increase the bed height of the first catalytic solid by at least about 20%, and
- recovering liquid product.
