以稻草为原料，在220℃下进行水热碳化1 h，并将得到的工艺水再循环使用。主要目的是系统研究工艺循环水中主要有机组分对水热炭燃料属性的影响以及演变机理。结果表明，随着水热碳化循环次数的增加，稻草逐渐转化为具有芳香族结构和丰富含氧官能团的水热炭。O/C和H/C分别从0.67和1.36下降到0.12和0.65。部分水热炭的高热值已达到中高发热量煤的质量等级，表明工艺水再循环对水热炭的化学结构、燃烧特性和燃烧行为有着显著影响。
Abstract：Using straw as raw material and carbonizes it under hydrothermal conditions at 220 ℃ for 1 hour, and the resulting process wastewater is recycled. The main purpose is to systematically study the influence and evolution mechanism of the main organic components in the process circulating wastewater on the properties of hydrothermal carbon fuel. The research results indicate that as the number of cycles after hydrothermal carbonization increases, rice straw gradually transforms into hydrothermal carbon with aromatic structure and rich oxygen-containing functional groups. O/C and H/C decreased from 0.67 and 1.36 to 0.12 and 0.65, respectively. The high calorific value of some hydrothermal carbons has reached the quality level of coal with medium to high calorific value. This indicates that process wastewater recycling has a significant impact on the chemical structure, combustion characteristics, and combustion behavior of hydrothermal carbon.
