Its mechanism is the use of anthraquinone in alkali conditions off proton surface forming 10 more stable carbon anion face, but because carbon anion and oxygen ion exist between testosterone and enolate type each other changes, cause reaction product complex, at least five, reaction selectivity, product yield, separation difficulties, and product purity is not high, therefore, using the type and quantity of alkali, phase transfer catalyst type, solvent, to optimize the selection process conditions so as to improve the yield target product.

其机理是利用蒽酮在碱存在的条件下脱去氢质子面形成10位较稳定的碳负离子面进行，但是因为碳负离子和氧负离子之间存在酮式和烯醇式的互变，导致反应复杂，产物至少有五种，反应选择性差，产物分离困难，产率低，且产品纯度不高，因此，利用对碱的种类和量的多少，相转移催化剂的种类，反应溶剂的选择，来优化反应工艺条件从而提高目标产物的产率。

The cokes are come from aromatics, colloids, asphaltene and Carbenes which are polycondensated and dehydrogenated. The processing of coking in the system are as follows: aromatics－→colloids－→asphaltene－→Carbenes－→cokes.(4) Coking can be avoided in the plasma reactor by feeding coal powder of 40～60 mesh (30%) and coal powder of less than 140 mesh (70%).

3结焦主要发生在等离子体反应较高温区，由煤中的芳香分、胶质、沥青质和碳青质缩聚脱氢形成；装置结焦形成的大体途径为：芳香分－→胶质－→沥青质－→碳青质－→焦质。

It is the common phenomenon that the industry wastewater is treated to be reused water, new industry water, desalted water, soft water or pure water for industrial production.
