The invention relates to a method for preparing a sulfonated carbon solid acid catalyst, which uses a sulfonic aromatic compound to replace sulfuric acid.

本发明涉及一种以磺酸基芳香化合物代替硫酸制备磺酸化的炭质固体酸 催化剂的制备方法。

This allows the catalyst to break down the remaining methane into solid carbon and hydrogen gas.

这使得催化剂能将余下的甲烷分解成固体碳和氢气。

Tests showed that the catalyst remains active for seven hours before it becomes choked up with solid carbon.

测试表明，这种催化剂若没有被碳消耗则7小时后仍具有活性。
