Abstract
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.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
103 words
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.
Claim 2
Dependent Claim
103 words
