Abstract
This invention relates to a process and an apparatus for producing a mixed feed stream for a steam reforming plant from a first feed stream containing methane and a second feed stream comprising higher hydrocarbons, olefins and diolefins. According to the invention, the required hydrogenation of the mono- and diolefins and the hydrodesulfurization of the organic sulfur compounds contained in the feed stream are carried out step by step under process conditions optimized in each case. Furthermore, the inlet temperature into the respective reaction zone is controlled such that overheating of the feedstocks is avoided, which otherwise leads to undesired coke deposits, cloggings and the accelerated deactivation of the catalysts used.
