摘要： This invention relates to a process for producing Caro's acid by reaction of at least 85% by weight sulfuric acid and at least 50% by weight hydrogen peroxide wherein the sulfuric acid and hydrogen peroxide are fed through separate feed lines into a funneling zone open to the atmosphere, the feed lines having air gaps between their ends and the funneling zone; continuing to introduce the sulfuric acid and the hydrogen peroxide into the funneling zone to flow and mix within the funneling zone, passing the resulting mixture by gravity flow into one end of a reaction zone whose size permits a pressure drop which is at least 8 times the theoretical pressure drop for such reaction zone and removing a mixture containing Caro's acid from the exit end of the reaction zone.

摘要： An exhaust gas treating method removes sulfur dioxide from exhaust gas containing at least sulfur dioxide and mercury by bringing the exhaust gas into contact with absorption liquid. Persulfate is added into the absorption liquid or alternatively, iodine gas is added to the exhaust gas before the exhaust gas is brought into contact with the absorption liquid. A high removal rate for both sulfur dioxide and mercury is stably maintained if the load of power generation and the composition of exhaust gas fluctuate.

摘要： Transition metal ions have the ability to increase the oxidation performance of the inorganic peroxy salts at room temperature by possibly lowering their activation energy or by producing more reactive free radicals. When two transition metal salts are used together to decompose dipersulfate, it provides synergistic oxidation activity, better than obtained by dipersulfate or dipersulfate with either copper or zinc alone. The transition metals mentioned are the water soluble salts of copper and zinc. Oxidation performance of sodium dipersulface in presence of catalytic amount of copper and zinc salts was determined by measuring the destruction of crystal violet dye at a wavelength of 589 nm.

摘要： Conventional plant to produce peroxomonosulphuric acid (Caro's acid) is large and emphasises extensive cooling, so that it is awkward to transport, can be cumbersome to install beside existing plant and can suffer from relatively expensive capital and/or running costs.In the present invention, Caro's acid is generated continuously in relatively small plant adiabatically, by introducing concentrated hydrogen peroxide into a stream of concentrated sulphuric acid in a reaction chamber dimensioned so that the throughput is very fast. In particularly suitable embodiments, the reaction chamber is annular at the points of introduction of the reagents, its width being greater in the vicinity of the hydrogen peroxide inlet than in the vicinity of the sulphuric acid inlet. The hydrogen peroxide inlet is preferably angled backwardly so that its encounter angle with the sulphuric acid stream is over 90.degree. to about 165.degree..
摘要翻译：生产过氧硫酸（Caro's acid）的传统工厂很大，并且强调大量的冷却，因此运输是尴尬的，安装在现有工厂旁边可能很麻烦，并且可能遭受相对昂贵的资金和/或运行成本。在本发明中，通过将浓缩的过氧化氢引入反应室中的浓硫酸流中，绝热地在相对较小的植物中连续生成Caro酸，其尺寸使得生产量非常快。在特别合适的实施方案中，反应室在试剂引入点处是环形的，其宽度在过氧化氢入口附近比在硫酸入口附近更大。过氧化氢入口优选地向后倾斜，使得其与硫酸流的碰撞角超过90度至约165度。
