摘要

将国槐园林废弃物分别在240、320、400、480 ℃下热解

进行工业分析、元素分析、热值分析及热重试验

选择燃烧特性最佳的作为生物炭原料

采用响应面法及蚁群算法对其成型工艺参数进行响应优化研究。结果表明

国槐园林废弃物热解温度为480 ℃时

固定碳含量67.67%

热值5713.70 kcal/kg

综合燃烧特性指数0.0944×10-8 mg2/K3·min2

挥发分析出特性指数0.1093×10-4 mg/K2·min

满足I级生物炭指标要求

是最佳成型原料

其最佳成型工艺参数为：温度84 ℃、压强111 MPa、黏结剂占比18%、含水率18%

在此条件下燃料密度及抗跌碎性分别为1.0347 gcm3及98.722%。

Abstract

The garden waste was pyrolyzed at 240 ℃

320 ℃

400 ℃ and 480 ℃

respectively

and industrial analysis

elemental analysis

calorific value analysis and thermogravimetric test were carried out to select the biochar with the best combustion characteristics as the raw material of biochar

and the response optimization of the molding process parameters was carried out using the response surface methodology and ant colony algorithm for the parameters of its molding process. The results show that when the pyrolysis temperature of garden waste is 480 ℃

the fixed carbon content is 67.67%

the calorific value is 5713.70

the comprehensive combustion characteristic index is 0.0944×

and the volatility analyzed characteristic index is 0.1093×

which meets the requirement of Grade I biochar and makes it the best raw material for molding. The optimal molding process parameters are as follows： the temperature is 84 ℃

the pressure is 111 MPa

the percentage of binder is 18%

and the water content is 18%. Under these conditions

the density and shatter resistance of the fuel were 1.0347 and 98.722%

respectively.
