1主要生产技术天然气、煤炭、焦炭、渣油、石脑油、乙炔尾气等都可以是生产甲醇的原料,但从20世纪50年代起,天然气逐步成为合成甲醇的主要原料,而在中国以煤炭为原料发展很快。根据资料,甲醇的热值为22.7GJ(0.776吨标准煤),大型煤制甲醇装置的平均综合能耗为1.54吨标准煤,热能转化率为50.4%;联醇的平均综合能耗高达2.73吨标准煤,热能转化率仅为28.4%。 1 The main production technology Natural gas, coal, coke, residual oil, naphtha, acetylene tail gas can be the raw material for the production of methanol, but from the 20th century, 50 years, natural gas is gradually becoming the main raw material for the synthesis of methanol, and in China with coal For the rapid development of raw materials. According to the data, the calorific value of methanol is 22.7GJ (0.776 tons of standard coal). The average comprehensive energy consumption of large-scale coal-to-methanol plant is 1.54 tons of standard coal, with the conversion rate of thermal energy being 50.4%. The average comprehensive energy consumption of the coal blending is as high as 2.73 tons Standard coal, thermal conversion rate of only 28.4%.
