And gave a brief introduction of a novel technology for green synthesis of chlorobenzoic acids by dioxygen oxidation of chlorotoluenes using metal-loporphyrins as biomimetic-catalysis.

The main research contents included establishment of molybdenum content detection method in reaction system, optimization of indirect electrooxidation process and decomposition molybdenite by oxygen oxidation process and so on.

Comparison about air-blown gasifier and oxygen-blown gasifier based on IGCC systems;
