Research Abstract |
We have proposed an efficient conversion method of low rank coals such as brown coals, which consists of hydrothermal extraction and subsequent hydrothermal gasification. The hydrothermal extraction at around 350℃ can convert low rank coals into upgraded coal having less moisture and larger heating value as well as small molecular weight compounds as extracts. The extracts are subsequently gasified to fuel gases such as methane and hydrogen under hydrothermal condition using Ni-loaded carbon catalyst developed by us. It was shown that the proposed method can convert low rank coals into upgraded coals, fuel gases, and clean water without a loss of heating value of the original coal.
