摘　　要：以稻秆和稻秆混聚乙烯为研究对象,经水洗后通过浸渍法对稻秆添加钾,采用上吸式固定床反应器,重点研究了钾含量对稻秆和稻秆混聚乙烯(聚乙烯占40%)水蒸气气化的影响。结果表明:温度为850℃,水蒸气流量为2.0 g/min,稻秆中钾含量从2×10^(-4)mol/g升高至8×10^(-4)mol/g时,反应5 min内,两种燃料的H_2和CO_2产量都相应提高,CO含量降低,但总产气量增加;反应25 min后,稻秆的总产气量、产氢气量增加率分别为18.28%和4.08%,稻秆混聚乙烯时的总产气量、产氢气量增加率分别为28.76%和25.15%。The influence of potassium content dipped into washing rice strawon steam gasification of rice strawand rice strawmixed with polyethylene（ 40%） was carried out in an up-suction fixed bed reactor. The results indicated that H2 and CO2 production of the two fuels correspondingly increased and CO decreased when the potassium content increased from 2 × 10^-4mol / g to 8 × 10^-4mol / g under 850℃ and steam flowrate of 2. 0 g / min within the first 5 minutes,while the total output gas production increased. The total output gas production rate and H2 production rate are increased by 18. 28%,4. 08% and 28. 76%,25. 15% respectively in 25-min gas reaction.
