摘要

摘要:
运用水热炭化工艺，研究不同温度（170~270 ℃）、停留时间（0~100 min）、料液比（1∶1、1∶3、1∶9）对餐厨废物水热反应减重的影响，并对运行参数进行优化。结果表明：升高温度，餐厨废物的减重率也随之提高，且减重率均在91%以上；随着停留时间的延长，减重率在20~40和80~100 min时会有小幅度的增长，在0~100 min的停留时间内减重率从83.90%增至86.80%；料液比的增加会使减重率下降，料液比为1∶9、1∶3、1∶1时，对应的减重率分别为91.60%~91.87%、86.20%~87.00%、83.90%~88.10%。液相产物COD测定结果表明，反应温度和料液比是影响液相产物COD的主要因素，随着反应的进行，液相产物COD先是逐渐减小并趋于平稳，后略有增加。试验得到的水热炭高位热值为30.50~31.90 MJ/kg，高于国家标准煤热值29.30 MJ/kg。

Abstract:
Using the hydrothermal carbonization process, the effect of varying temperatures (170 to 270 ℃), residence time (0 to 100 min), and solid-water ratios (1∶1, 1∶3, and 1∶9) on the weight reduction of hydrothermal reaction of kitchen waste was researched, and the operating parameters were optimized. The findings of this test revealed that as the temperature rose, the weight loss rate of kitchen waste increased, reaching a value of over 91%. The weight loss rate increased slightly as the residence time extended from 20 to 40 minutes and from 80 to 100 minutes. During the residence times of 0 to 100 minutes, the weight loss rate increased from 83.90% to 86.80%. A higher solid-water ratio would have a negative impact on the weight loss rate. The corresponding weight loss rates were 91.60% to 91.87%, 86.20% to 87.00% and 83.90% to 88.10% at solid-water ratios of 1∶9, 1∶3 and 1∶1, respectively. The solid-water ratio and the reaction temperature were the main factors affecting COD of the liquid products, which initially gradually decreased and leveled off as the reaction progressed before slightly increasing. This was demonstrated by the results of COD measurement of the liquid products. The higher heating value of hydrochar obtained in the test was 30.50 to 31.90 MJ/kg, which was greater than the national standard coal calorific value of 29.30 MJ/kg.
