Abstract:
A Fischer-Tropsch catalyst activation system including separation apparatus configured for separating a product gas comprising primarily hydrogen from a gas stream comprising hydrogen, an activation reactor fluidly connected with the separation apparatus via an activation gas inlet line whereby the product gas may be introduced into the activation reactor, and a circulation loop fluidly connecting a gas outlet of the activation reactor with the activation gas inlet line or with another gas inlet of the activation reactor and fluidly connecting the activation reactor with one or more apparatus configured for removal of H2O. A method of activating a Fischer-Tropsch catalyst is also provided.
Abstract:
A process for producing liquid and, optionally, gaseous products from gaseous reactants comprises feeding gaseous reactants into a slurry bed of solid particles suspended in a liquid; allowing the reactants to react as they pass upwardly through the slurry bed, thereby to form liquid and, optionally, gaseous products; and separating liquid product from the solid particles by passing, in a filtration zone within the slurry bed, liquid product through a filtration medium in a first direction, so that a cake of the solid particles forms on the filtration medium. The passage of liquid product through the filtering medium is interrupted. The filtering medium is then backflushed by passing a flushing fluid through the filtering medium in a second direction, opposite to the first direction, for at least portions of the periods that the liquid product passage is interrupted, thereby to dislodge the cake from the filtering medium.
