Abstract
The invention relates to a process and an apparatus for producing an olefin-containing feed stream for a steam reforming plant. According to the invention, the olefin-containing hydrocarbon starting material is for this purpose heated, vaporized and catalytically hydrogenated. The hydrogenation product stream obtained is separated in a separation apparatus into a gaseous reforming feed stream, which is fed to a steam reforming plant, and a gaseous recycle stream. Here, the entry temperature of the hydrogenation input stream into the hydrogenation reactor is regulated via the degree to which it is heated and/or via the size of the recycle stream. Safe operation of the hydrogenation reactor over a wide range of olefin contents in the hydrocarbon feed is made possible in this way.
