Abstract

The influence of the process conditions of hydrothermal carbonization (temperature, process duration, the presence of a catalyst (citric acid), and the raw material/water ratio) on the properties of hydrochar obtained from peat was studied. The following regularities were found: the weight and energy yields of the hydrochar decreased with the temperature and reaction time. An increase in the reaction temperature from 170 to 230°С contributed to an increase in the calorific value (from 23.86 to 26.8 MJ/kg for the gross calorific value and from 22.26 to 25.02 MJ/kg for the net calorific value). An increase in the reaction time from 1 to 6 h also led to an increase in the calorific value (from 22.72 to 24.61 MJ/kg for the gross calorific value and from 24.61 to 23.20 MJ/kg for the net calorific value). The addition of a catalyst increased the gross and net calorific values of hydrochar by 6 and 6.2%, respectively.

水热碳化技术在改善泥炭能量特性中的应用

摘要

研究了水热碳化的工艺条件(温度,工艺持续时间,催化剂(柠檬酸)的存在以及原料/水的比例)对从泥炭中获得的水焦炭性能的影响。发现以下规律:水炭的重量和能量产率随温度和反应时间而降低。反应温度从170升高到230°С有助于热值的增加(总热值从23.86到26.8 MJ / kg,净热值从22.26到25.02 MJ / kg)。反应时间从1小时增加到6小时也导致热值增加(总热值从22.72增至24.61 MJ / kg,净热值从24.61增至23.20 MJ / kg)。
