| description | To provide a method and system for more quickly purging a flammable gas of hydrocarbons adsorbed on an adsorbent in a hydrogen production process that includes a desulfurization step and a steam reforming step.SOLUTION: The present invention provides a method for purging hydrocarbons adsorbed on an adsorbent in a hydrogen production process, the method including (i) a desulfurization step in which sulfur or sulfur compounds, which are impurities, are removed from a feed stream containing sulfur or sulfur compounds and hydrocarbons by using an adsorbent, and (ii) a steam reforming step in which the desulfurized feed stream containing hydrocarbons is subjected to steam reforming with heating by a burner in the presence of a steam reforming catalyst to obtain a mixture of carbon monoxide and hydrogen. In the purge method, a carbon dioxide-containing gas, preferably a carbon dioxide-containing combustion exhaust gas discharged from the burner in the steam reforming step, is used to purge the hydrocarbons adsorbed on the adsorbent.SELECTED DRAWING: Figure 2
【課題】脱硫工程と水蒸気改質工程を含む水素製造プロセスにて、吸着材に吸着した炭化水素の可燃性ガスをより迅速にパージする方法、システムを提供する。【解決手段】本発明は、（ｉ）不純物である硫黄または硫黄化合物、および炭化水素を含む供給流から、吸着材を用いて硫黄または硫黄化合物を除去する脱硫工程、ならびに（ｉｉ）炭化水素を含む脱硫済み供給流を、水蒸気改質触媒の存在下、バーナによる加熱を伴う水蒸気改質にかけて一酸化炭素および水素の混合物を得る水蒸気改質工程を含む水素製造プロセスにおいて、吸着材に吸着した炭化水素をパージする方法であって、二酸化炭素を含むガスを用いて、好ましくは、水蒸気改質工程にてバーナから排出された二酸化炭素を含む燃焼排ガスを用いて、吸着材に吸着した炭化水素をパージするパージ方法である。【選択図】図２ |
