摘要：

The conceptual design of a coal gasification system for the production of hydrogen is undertaken here using the PRO II Simulation program The operating conditions for the gasifier were tuned to between 1200 degrees C-1500 degrees C 15 atm-30 atm and to a feed molar ratio of C H2O O-2 = 1 0 5-1 0 25-0 5 The refinery temperature and pressure were kept at 550 Cand 24 5 atm The syngas produced goes to water gas shift (WGS) reactors operated at 400 degrees C 24 atm (HTS) and 250 degrees C 23 5 atm (LTS) The production of hydrogen was found to be independent of the concentration of steam in the feed However when other operating conditions are constant the hydrogen output changes dramatically with changes to the concentration of O-2 in the feed The optimal operating conditions for the production of hydrogen by the gasification of Drayton coal were found to be 1500 degrees C 25 atm and a feed ratio C H2O O-2 = 1 0 58 0 43 (C) 2010 Published by Elsevier Ltd on behalf of Professor T Nejat Veziroglu
