摘要:能源危机使生物燃料酒精应用前景广阔,但现行工业上的酒精精馏工艺能耗较大,阻碍了
燃料酒精工业的发展。本文探讨了利用微波作为热源分离生物酒精的工艺。在实验室条件下探索
出一套多功率分时段加热组合与分子筛脱水结合的流程,使酒精蒸馏工段单位能耗降低到现行工
业水平的 60%,经气相色谱分析,所得产物浓度达到 90%到 95%之间,再经过 3A 分子筛脱水,
得到 %的乙醇,并尝试用微波来活化分子筛,取得了良好的效果。

Abstract:The energy crisis made the application of bio-fuel ethanol e more popular.
Current industrial alcohol distillation need a process of large energy consumption, which e
an obstacle in the development of fuel alcohol industry. In this paper, we discussed the separation
of bio-ethanol by the use of microwave as a heat source. The experimental results demonstrated
that the microwave distillation separation of bio-alcohol, to fill in the column chromatography
with molecular sieve in order to produce high-purity ethanol (about 99%), as well as
