Zhongcheng expands hydrogen peroxide capacity. (Project News).Guangdong Zhongcheng Chemical Co., Ltd. invested RMB RMB Right Mouse Button RMB Regional Management Board (USACE) RMB Rolf Maier Bode (musician, band) RMB Ren Min Bi (currency of People's Republic of China) 245 million in building a 25 000 t/a 100% hydrogen peroxide hydrogen peroxide, chemical compound, H2O2, a colorless, syrupy liquid that is a strong oxidizing agent and, in water solution, a weak acid. It is miscible with cold water and is soluble in alcohol and ether. unit. Recently, it comfortably passed experts' appraisals and technology evaluation. The actual output has exceeded the designed capacity, reaching 35 000 t/a. The unit uses the cost-effective hydrogen resource, which is yielded as a by-product in the production of sodium hydrosulfite. It employs technology producing hydrogen peroxide developed by Liming Research Institute of Chemical Industry (LRICI), using palladium anthraquinone anthraquinone /an·thra·quin·one/ (an?thrah-kwin´on) 1. the 9,10 quinone derivative of anthracene, used in dye manufacture. 2. any of the derivatives of this compound, some of which are dyes. as catalyst. It also applies live pressure adsorption adsorption, adhesion of the molecules of liquids, gases, and dissolved substances to the surfaces of solids, as opposed to absorption, in which the molecules actually enter the absorbing medium (see adhesion and cohesion). hydrogen preparation technology developed by the Southwest Research and Design Institute of Chemical Industry. At present, the unit can provide 27.5%, 35%, 50% and 70% concentration of hydrogen peroxide while the energy and material consumption have been reduced gradually. |
