Patent ID: 7019038

Claim:
A method for increasing the mass transfer of a reactant gas component into a liquid product comprising: feeding a reactant gas to a catalytic reactor; converting at least a portion of the reactant gas on a synthesis catalyst to generate in the catalytic reactor a liquid product having a product average molecular weight; withdrawing from the catalytic reactor a liquid outlet stream comprising at least a portion of the liquid product, the liquid outlet stream having an outlet average molecular weight lower than the product average molecular weight; and feeding to the catalytic reactor a hydrocarbon feedstream with a feed average molecular weight of less than the outlet average molecular weight, such that the difference between the product average molecular weight and the outlet average molecular weight favors a mass transfer increase of at least one component of the reactant gas into the liquid product inside the catalytic reactor, wherein the ratio of the hydrocarbon feedstream flow rate over the liquid outlet stream flow rate is between 0.14 to 0.95.
