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.

我们提出了一种低煤阶煤如褐煤的有效转化方法，该方法包括水热提取和随后的水热气化。在350℃左右进行水热抽提，可以将低阶煤转化为水分含量低、热值大的改质煤，并可得到小分子量的抽提物。萃取物随后在水热条件下使用我们开发的负载镍的碳催化剂气化为燃料气体，如甲烷和氢气。结果表明，该方法可以将低阶煤转化为提质煤、燃气和清洁水，而不损失原始煤的热值。
