Abstract

The influence of the thermophysical characteristics of biochars obtained by hydrothermal carbonization of peat on the yield and composition of producer gas in the course of its steam–air gasification was studied. It was established that an increase in the temperature of hydrothermal treatment of peat facilitated not only an increase in the yield of gas but also an increase in its qualitative characteristics, namely, calorific values. Long-term processing of peat raw materials (50 h) during hydrothermal carbonization led to too deep deoxygenation of the raw materials and adversely affected the quality of the resulting producer gas.

泥炭水热炭化生产生物炭的气化

摘要

研究了泥炭水热炭化制得的生物炭的热物理特性对其蒸汽-空气气化过程中发生炉煤气产率和组成的影响。已经确定，泥炭水热处理温度的升高不仅促进了气体产量的增加，而且还促进了其质量特征的增加，即热值。泥炭原料在水热碳化过程中的长期处理（50 小时）导致原料脱氧过深，对产生的发生炉煤气质量产生不利影响。
