摘要: Abstract As a result of stricter environmental regulations worldwide, hydrogen is becoming an important clean energy source. For it to replace fossil fuels in mobile applications, however, will require the creation production and delivery infrastructure equivalent one that currently exists for fuels, which immense task. alternative interim step towards new economy, various groups are studying steam reforming methane (SRM) on-board generation hydrogen, or on site production, order alleviate need compressed liquid storage. One such technology hybrid adsorbent-membrane reactor (HAMR) system, couples reaction membrane separation steps with adsorption and/or permeate side. Our early studies involved development mathematical model HAMR system applied through SRM. Recently, experimental investigations water-gas shift reaction, using microporous membranes hydrotalcite-type CO 2 adsorbents, were carried out validate design model. In this paper, we focus practical process aspects process. A continuous, four-bed scheme proposed investigated both experimentally modeling studies.
