Reaction Simulation of Hydrogen (H2) Production from Steam by Plasma
Abstract
Simulation hydrogen production from water vapour using CHEMKIN PRO, then plasma PSR selected in the modelling approach. The PMR consisted of a glass tube and a hydrogen separation membrane module made by Nippon Seisen Co., Ltd. In this module, a palladium alloy membrane of 20 μm thickness was carefully welded inside a thin punched metal (SUS 304). The hydrogen separation membrane module served as the high-voltage electrode of the PMR. The PMR length was 400 mm, whereas the grounded electrode length was 300 mm. The gap length was 1.5 mm, same as that in the PR. The gap volumes of the PR and PMR were 67.0 and 51.6 cm3, respectively. Problem type using solve gas energy equation with transient solver. Bulk activity equations in turn off condition, with bubbling temperature range 40, 50, 60, and 70 oC. The flow rate that used 0,1, 0,5, and 1,0 L/min, applied voltage 7-11 kV, and power 70-250 W. The reaction mechanism used in this simulation is the Skreiberg Models.
