煤焦油催化加氢催化剂再生的试验与研究

The Testing and Research on the Catalyst Regeneration in the Production of Catalytic Hydrogenation of Coal Tar

煤焦油催化加氢是提高煤焦油经济效益的重要手段,催化剂再生对降低煤焦油催化加氢生产成本具有重要意义。本文实验研究了高温煅烧再生、溶剂洗涤再生等方法,确定了最佳的再生方法和参数。

The catalytic hydrogenation of coal tar is an important means for the economic efficiency im-provement of coal tar, of catalytic hydrogenati and the catalyst regeneration on of coal tar. In the paper, regeneration and solvent washing regeneration were parameters were determined at last. is of great significance to reduce the production cost the methods including high temperature calcination studied, and the optimal regeneration methods and
