Site hydroisomerization of synthetic hydrocarbon liquid in Tropsch reactor - slurry Fischer

摘要

In hydrocarbon synthesis reactor, in a slurry Fischer-Tropsch hydrocarbon synthesis process for synthesizing the liquid hydrocarbons from synthesis gas, in the downcomer reactor in one or more immersed in the slurry body in the synthesis reactor, It also performs the hydroisomerization of synthetic hydrocarbon liquid containing slurry liquid. Preferably, the monolithic catalyst is used in the hydroisomerization. At least some circulation of slurry from the slurry body down around through the downcomer reactor is achieved by density difference driving liquid pressure. The density difference driving liquid pressure is effected by removing from the slurry sent to the down tube, the gas bubbles. Preferably, before the slurry is in contact with the catalyst, I do also removal of the catalyst particles. hydroisomerization occurs without synthesis reactor while continuing to produce a hydrocarbon, to inhibit the hydrocarbon synthesis reaction.
