Abstract

The invention relates to a method for dealing with product fluid flows that arise in the catalytic hydrogenation of liquid inflows in laboratory catalysis devices. The liquid inflows are preferably hydrocarbons that contain compounds containing sulfur and containing nitrogen as contaminants. The hydrogenation is used to convert the contaminants to hydrogen sulfide and ammonia, which in this form are easy to separate from the other components of the liquid inflow. The product fluid flows are contacted with an inert-gas flow, wherein the flow rate of the inert gas is several times greater than the flow rate of the product fluid. By means of the method according to the invention, the formation of deposits in lines of the region on the outlet side of the reaction chamber can be effectively prevented.
