以提供2-甲基四氢呋喃的连续制造方法。 该方法包括从所述第一反应区中引入气化糠醛和氢气的第一反应区中，引入和执行初级催化氢化反应，该气体进入第二反应区，次级催化氢化 进行反应混合物冷却并从第二反应区冷凝的气体，2-甲基 - 包括获得四氢呋喃，并在第一反应区中填充有用于醛还原酶的催化剂，所述 在芳烃饱和的氢化中使用的催化剂被填充到第二反应区。 毒性低，使用催化剂可用廉价且容易地，在低压力或环境压力，气相连续反应生产高纯度加入2-MeTHF从糠醛，高压，传统的高投资和高风险2- 改变的MeTHF生产工艺，它降低了现有技术中使用的高毒性和成本催化剂。 生产工艺简单，投资小，风险和每单位时间的原料糠醛低的大的处理量和产率是高的，得到的粗产物的纯度高，杂质容易分离。 点域1

To provide a continuous method for producing 2-methyl tetrahydrofuran. The method includes introducing a gas of furfural and hydrogen to the first reaction zone, introducing a step of performing primary catalytic hydrogenation reaction, the gas from the first reaction zone into the second reaction zone, a secondary catalytic hydrogenation and performing the reaction, allowed to cool condensed gas from the second reaction zone, 2-methyl-comprising obtaining a tetrahydrofuran, and the first reaction zone is filled with catalyst used in aldehyde reduction, the the catalyst used in the hydrogenation of aromatics saturation is filled into the second reaction zone. Low toxicity, using a catalyst that can be available at low cost and easily, in a low-pressure or environmental pressure, by a vapor phase continuous reaction to produce a high-purity 2-MeTHF from furfural, high pressure, traditional of high investment and high risk 2- changing the MeTHF of the production process, it reduces the high toxicity and cost catalyst used in the prior art. Production process is simple, the investment is small, risk and large processing amount of furfural feedstock per unit time low and the yield is high, the purity of the crude product obtained is high, impurities are easily separated.
