摘要  自主设计并搭建了一套超重力反应装置以研究超重力技术在蒽醌法生产双氧水上的应用。实验分别考察蒽醌加氢在超重力单程加氢操作和循环加氢操作下的氢效以及时空收率。实验结果表明在超重力反应系统中,当转速在350~400 r/min时加氢效率最高;在40~60 ℃,0.1~0.3 MPa的条件下,随温度和压力升高氢效有所提高。同时实验发现在相同反应条件下,循环加氢的操作方法虽然可以得到较高的氢效但同时极大地降低了时空收率。用超重力技术单程加氢的操作方法可以得到的产品时空收率为27.9 g(H2O2)/L(cat.)·h,远高于同条件下的采用固定床加氢的产品时空收率(12.7~16.5 g(H2O2)/L(cat.)·h)。因此本文认为采用连续的单程加氢的超重力技术在蒽醌法制备双氧水上更具经济性。

Abstract

  This paper describes Higee(High Gravity) technology which produces hydrogen peroxide with an independently designed and constructed Higee reaction system in the anthraquinone process. This Higee equipment consists of 5 parts: raw material tank, product tank, working pump, temperature-controlled water bath and the rotating packed bed (RPB) reactor. And it is also comprised of two circulatory systems, the raw material heat circulatory system and the working liquid continuous reaction circulatory system. The raw material heat circulatory system comprises a raw material tank, working pump and temperature-controlled water bath. Working fluid pumped from the raw material tank by the working pump flows back to the raw material tank through the temperature-controlled water bath achieving a rapid heating cycle of the working fluid. The working liquid continuous reaction circulatory system includes all those 5 parts. Working fluid is pumped from raw material tank, and then raw material flows back through temperature-controlled water bath, Higee reactor and product tank. This whole process is called the working fluid continuous reaction. The experimental results show that the appropriate rotation speed has improved the hydrogenation efficiency significantly, and the optimum speed is 350~400 r/min. Simultaneously, the effect of temperature and pressure on the Higee reaction system is similar to that of a fixed bed reactor system. Circulatory hydrogenation operation can achieve a higher hydrogenation efficiency, and in the meanwhile greatly reduce the space-time yield. Compared with the fixed bed production technology (12.7~16.5 g(H2O2)/L(cat.)·h), Higee production technology by one-way hydrogenation has a higher space-time yield (27.9 g(H2O2)/L(cat.)·h), and therefore successive one-way hydrogenation is more economical and has more research value.
