摘要
为了验证甲醇同系化制乙醇的可行性,并为相关的实验研究提供理论依据,采用HSC Chemistry软件对甲醇同系化制乙醇反应进行热力学分析,考察反应压力、反应温度和氢碳比对原料转化率和产物选择性等指标的影响。结果表明,在压力为4 MPa、温度为250℃、氢碳比为2.0∶1(MeOH/CO比为0.1∶0.9)最佳反应条件下,乙醇选择性为97.00%,氢气转化率为40.00%,一氧化碳转化率为100.00%,甲醇转化率为100.00%。甲醇同系化制乙醇实验研究表明,乙醇选择性与热力学理论值还有些差距,催化剂对于原料转化率和乙醇选择性还有待提高。
In order to verify the feasibility of ethanol synthesis by methanol homologation and provide theoretical basis for related experimental research,a thermodynamic analysis of methanol homologation to ethanol was carried out by using HSC chemistry software.The effects of reaction pressure,reaction temperature and hydrogen carbon ratio on the conversion of raw materials and the selectivity of products were investigated.The results showed that the best conditions for the reaction were pressure 4 MPa,temperature 250℃,hydrogen carbon ratio 2.0∶1(MeOH/CO was 0.1∶0.9),the selectivity of ethanol was 97.00%,the conversion of hydrogen was 40.00%,the conversion of carbon monoxide was 100.00%,the conversion of methanol was 100.00%.The experimental study of ethanol synthesis by methanol homologation shows that there is a gap between the selectivity of ethanol and the theoretical value of thermodynamics.The catalyst for the conversion of raw materials and the selectivity of ethanol still need to be improved.
