摘要： Hydrocarbons are preheated, particularly for a hydrodesulfurization process by first heating the hydrocarbon stream to produce a vapor and a liquid stream, thereafter superheating at least some of the vapor phase and mixing the superheated vapor phase with the liquid phase to generate the hydrocarbon feedstream at the desired temperature. By this procedure only the evaporated hydrocarbons are subjected to a high temperature, but not the heavier hydrocarbons.
