Selectively permeable membrane reactor and hydrogen production method using a selectively permeable membrane reactor

摘要

In the hydrogen production process of the present invention, A [ml / min], the amount of hydrogen that has not passed through the selectively permeable membrane (non-permeated hydrogen amount of hydrogen separated by passing through the permselective membrane (permeated hydrogen amount) when as B [ml / min] amount), the value of the hydrogen recovery is defined by the following equation becomes a 60~99%, _(CO 2), one the partial pressure of carbon dioxide at the outlet of the reaction tube When the (CO) and the partial pressure of carbon oxides, and to K the equilibrium constant for the disproportionation of carbon monoxide in the reaction tube temperature, under the condition that the value defined by the following equation α is 0.6 or more I do the production of hydrogen. Hydrogen recovery rate = 100 × {A / (A + B)} α ₌^{(CO 2) / (CO) 2} / K
