糠醛渣是将粉碎的玉米穗轴以4%稀硫酸处理,经加热蒸馏制得糠醛后剩下的废渣。凡以玉米穗轴为原料生产糠醛的工厂,每年都有这种大量废渣排出。以朝阳县化工厂为例,每年排出约5000吨。该厂往年这种废渣主要做为民用燃料廉价处理。根据辽宁省糠醛出口座谈会提供的经验,这种废渣用做肥料大有可为,它不仅对农作物有显著的增产效果,而且对土壤有较好的改良作用。为了明确这种废渣在朝阳地区主要土类上对 Furfural residue is crushed corn cob 4% sulfuric acid treatment, the residue obtained after heating distillation furfural residue. Where the corn cob production plant furfural raw material, each year have a large number of waste discharge. In Chaoyang County Chemical Plant, for example, discharged about 5,000 tons per year. The plant in the past this type of waste as a civilian fuel cheap treatment. According to the experience gained from the symposium on furfural export in Liaoning Province, this kind of residue can be used as a fertilizer.
