1. steam methane reforming method, it comprises:

  • Heating contains the feed stream of alkene and hydrogen to being not more than about 600 ℃

    temperature;

    Hydrogen in the feed stream is contacted with the catalyzer that can promote hydrogenation and partial oxidation reaction with alkene, do not make described hydrogen and alkene carry out catalyzed reaction and generate the intermediate product logistics that comprises the stable hydrocarbon that forms by hydrogenation of olefins under the situation of oxygen adding, the heating of feed stream is sufficient and/or the concentration of alkene in feed stream is enough, makes the intermediate product logistics produce under greater than about 400 ℃

    temperature;

    WithMake to small part and in steam methane reformer, react by reformer feed logistics and steam stream that the intermediate product logistics forms, thereby obtain the syngas product logistics, this syngas product logistics has the hydrogen that more manys mole and comprises carbon monoxide, water and carbonic acid gas than feed stream;

    The catalyzed reaction of hydrogen and alkene in containing the reactor of catalyzer greater than about 10, carry out under 000/ o'"'"'clock the air speed and under the situation of hydrogen with q.s, make the reformer feed logistics have alkene content, by volume based on the butt meter less than about 0.5% alkene.
