| 摘 要： | 将铜基催化剂CNZ-1和分子筛HZSM-5按一定比例,采用机械混合法制成二甲醚水蒸气重整催化剂,分别考察了水和二甲醚流量、反应温度、催化剂用量等对二甲醚水蒸气重整制氢的影响.结果表明:常压条件下,随着二甲醚流量增大,氢气的产量先变大再变小;在250～500℃的温度范围内,随着反应温度的升高,氢气的产率增大,二甲醚转化率最高可接近100%;CO体积分数随着反应温度的升高而减小;试验条件下,加大催化剂用量对氢气的产率影响不大,但可大幅度提高二甲醚的转化率.

| Abstract: | The performance of stream reforming for rich hydrogen co-gas by dimethyl-ether(DME)was experimental studied.The multiunit catalyst which was formed with copper-based catalyst(named CNZ-1) and aluminium/zinc based molecular sieve(named HZSM-5) by means of mechanical mixing,was used.The parameters such as flow rate of reactants including water steam and DME,the reaction temperature as well as the catalyst amount influence on the reforming performance were investigated.Results show that under normal pressure,w... |
