Treatment method of waste aluminum oxide in anthraquinone process hydrogen peroxide production process

The invention discloses a treatment method of waste aluminum oxide in an anthraquinone process hydrogen peroxide production process. The waste aluminum oxide is added into raw materials of a coal gasification process, then the waste aluminum oxide is sent to a gasification furnace to generate a gasification reaction, organic components in the waste aluminum oxide react to generate carbon monoxideand hydrogen, and inorganic components are discharged along with a gasification device slag system. According to the method, the waste aluminum oxide is added into feed coal of the coal gasification process, through combined use of a hydrogen peroxide device and the coal gasification device, hazardous wastes (waste aluminum oxide pellets) are harmlessly treated, meanwhile, carbon monoxide and hydrogen generated by the reaction can be used as components of coal gas, and win-win benefits are achieved. 本发明公开了一种蒽醌法过氧化氢生产过程中废氧化铝的处理方法，所述废氧化铝添加至煤气化工艺的原料中，再送至气化炉发生气化反应，废氧化铝中的有机成分反应生成一氧化碳和氢气，无机成分随气化装置渣系统排出。本发明将废氧化铝添加至煤气化工艺的原料煤中
