Advances in the production technology of hydrogen peroxide

This article mainly summarizes various aspects of hydrogen peroxide(H2O2)production through the anthraquinone route,including hydrogenation catalysts,working solution,regeneration technique,hydrogenation reactors,and environmental protection.The advances and breakthrough of SINOPEC in the production of H2O2 through the anthraquinone route is presented in this review,highlighting recent innovative technology on these aspects developed independently.The technical prospect and scientific challenges associated with the direct synthesis method from hydrogen and oxygen are also briefly discussed.

过氧化氢生产装置氢化工序优化控制

对6万t/a蒽醌法过氧化氢生产装置中影响氢化反应的各种因素(包括温度、压力、流量、工作液组分、钯催化剂)进行优化控制,取得了钯催化剂连续使用21个月的效果。

Treatment of anthraquinone dye wastewater by hydrolytic acidification-aerobic process

Experiment on microbial degradation with two kinds of biological process, hydrolytic acidification-aerobic process and aerobic process was conducted to treat the anthraquinone dye wastewater with COD Cr concentration of 400 mg/L and chroma 800. The experimental result demonstrated that the hydrolytic-aerobic process could raise the biodegradability of anthraquinone dye wastewater effectively. The effluent COD Cr can reach 120170 mg/L and chroma 150 which is superior to that from simple aerobic process.

6万t/a双氧水生产装置改造
