Process for producing feed stream for steam reforming plant

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 the 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 itis 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. 本发明涉及一种用于生产用于蒸汽重整设备的含有烯烃的进料流的方法和装置。根据本发明，为此目的，将含有烯烃的烃起始材料加热、蒸发和催化氢化。将所获得的氢化产物流在分离装置中分离成被进料到蒸汽重整设备中的气态重整进料流以及气态再循环流。在此，进入氢化反应器的氢化输入流的进入温度经由其被加热的程度和/或经由该再循环流的大小来调节。以这种方式使得可能在该烃进料中宽范围的烯烃含量内安全操作该氢化反应器。
