To introduce application status and illustrate the good utilisation potential of biomass pyrolytic polygeneration using retort reactors, the properties of major products and the economic viability of commercial factories were investigated. The capacity of one factory was about 3000t of biomass per year, which was converted into 1000t of charcoal, 950,000Nm(3) of biogas, 270t of woody tar, and 950t of woody vinegar. Charcoal and fuel gas had LHV of 31MJ/kg and 12MJ/m(3), respectively, indicating their potential for use as commercial fuels. The woody tar was rich in phenols, while woody vinegar contained large quantities of water and acetic acid. The economic analysis showed that the factory using this technology could be profitable, and the initial investment could be recouped over the factory lifetime. This technology offered a promising means of converting abundant agricultural biomass into high-value products.
为了介绍热解多联产技术在回转窑中的应用现状，说明其良好的利用潜力，考察了主要产品的特性和商业工厂的经济可行性。该工厂的产能约为每年 3000 吨生物质，可转化为 1000 吨木炭、950000Nm(3)沼气、270 吨木焦油和 950 吨木醋液。木炭和燃料气的低热值分别为 31MJ/kg 和 12MJ/m(3)，表明它们有作为商业燃料的潜力。木焦油富含酚类物质，而木醋液则含有大量的水和乙酸。经济分析表明，采用该技术的工厂可以盈利，初始投资可以在工厂寿命期内收回。该技术为将丰富的农业生物质转化为高价值产品提供了一种有前途的方法。
