一、概述我厂是生产糠醛的巾型企业,在糠醛生产过程中,吨糠醛耗煤7吨,年产糠醛800吨耗煤5600吨,吨煤价格按50元计,仅煤一项成本就28万元。全国一百多家糠醛厂,一九八一年生产糠醛3万吨,耗煤21万吨。另一方面,以玉米芯、棉子壳为原料经硫酸催化水解蒸留出糠醛后的废渣,堆积如山,需外运处理,污染严重。因此,如何实现以废渣为燃料,变废为宝,成了我们研究的主要课题。 I. Overview Our factory is the production of furfural towel enterprises, in furfural production process, tons of furfural coal consumption of 7 tons, with an annual output of 800 tons of furfural 5600 tons of coal, tons of coal prices by 50 dollars, only a cost of coal 280,000 yuan. More than one hundred furfural plants nationwide produced 30,000 tons of furfural in 1981 and consumed 210,000 tons of coal. On the other hand, waste residue from the fermentation of corncobs and cottonseed as raw materials after the catalytic hydrolysis of sulfuric acid to furfural is piled up and needs to be transported out of the country and seriously polluted. Therefore, how to achieve the waste as a fuel, turning waste into treasure, has become our main research topic.
