Vinyl chloride monomer plant exhaust treatment catalyst

. Not available because of the spontaneous combustion of exhaust gas, volume is great, from the equipment and running costs to consider, deal with the ideal catalyst for combustion. In order to solve has been considered difficult to handle through the catalyst of chlorinated VOC combustion of the subject, I developed a new catalyst research,[link widoczny dla zalogowanych], process and equipment design for the juice, and in 2001 began to operate. 2. Summary of collection, including vinyl chloride plant, including the oxidation of chlorinated VOC emissions from the exhaust, the purification, from which recovery of thermal energy (steam) and hydrochloric acid. 3. Decomposition of effects on performance of VOC content> 99.9% biphenyl cyclohexyl highly selective hydrogenation of benzene microwave assisted extraction of glycyrrhizic acid cyclohexyl benzene is an important intermediate. Widely used in liquid crystal,[link widoczny dla zalogowanych], plastic, coatings, adhesives and other fields. Phenyl Cyclohexane Liquid Crystals with a high chemical stability,[link widoczny dla zalogowanych], photochemical stability, low viscosity and excellent physical properties and other characteristics, is an ideal material for one of the display. Cyclohexyl benzene can also be used to prepare two common chemical intermediates phenol and cyclohexanone. New technology developed by our group. With biphenyl as raw materials, heterogeneous catalytic hydrogenation step reaction the yield of benzene ring has more than 99%. Cheap and easily obtained catalyst, non-toxic pollution, low cost and recyclable. The process can be relatively low temperature and pressure, to achieve rapid high-biphenyl cyclohexyl benzene selective hydrogenation. The process is short, low energy consumption; solvent can be recycled, no emissions pollutants; device easy to operate. No corrosion, durable,[link widoczny dla zalogowanych], there are considerable economic benefits. Investment in production capacity can be resized with its equipment in the pressure reactor made of stainless steel (2MPa). Biphenyls from the pyrolysis of raw materials dehydrogenation of benzene in the system. Well below the price of cyclohexyl benzene, a larger spatial profits. Pharmacological effects of licorice licorice acid is an important active ingredient. More mature now glycyrrhizin extraction method is mainly used to slice licorice mixed solvent of ethanol and ammonia soaking at room temperature, reflux or add ultrasonic assisted extraction; and then use the crystal or (ion exchange) adsorption, was purified. The disadvantage is time-consuming extraction process, high energy consumption; purification operation cumbersome and required repeated purification. The technology uses microwave-assisted extraction coupled leaching and extraction of glycyrrhizic acid, greatly reducing the extraction time, reduced energy consumption; after treatment using a stripping solvent extraction process of refining purified glycyrrhizin. Solvent can be recycled. Simplify the separation and purification steps, reducing the refining costs. Glycyrrhizic acid and its derivatives as pharmaceuticals,[link widoczny dla zalogowanych], food additives and cosmetics additives, has a broad market. Some manufacturers of domestic crude glycyrrhizic acid has been difficult to meet international market demand, severely restricted the export of glycyrrhizin. The technology to provide low-cost access to refined glycyrrhizin a feasible way
