Oxycombustion process for heating a feedstock

摘要

The invention relates to a method for treating a feed containing hydrocarbons with hydrogen wherein a fuel is combusted in a furnace by means of one or more burners, said feed is preheated by indirect heat exchange with the reaction products and/or the reaction heat from the combustion of said fuel to obtain a preheated feed, said preheated feed is passed in a reactor containing a catalyst and said preheated feed is treated with hydrogen in said reactor and wherein said fuel is combusted in a reaction with an oxidant comprising more than 21 % by volume of oxygen.
