The main function of SD paraffin wax and microcrystalline wax hydrogenation catalyst is to deep desulfurization and denitrification, and to reduce the content of polycyclic aromatic hydrocarbons in paraffin and microcrystalline wax products to less than 2μg/g, so as to meet the requirements of nontoxic and zero damage to human body. . The catalyst was successfully applied to Fushun Petrochemical's first high-pressure hydrogenation unit in China, and its product quality met the US Food and Drug Administration (FDA) international certification quality standard.
The LY-9802 pyrolysis gasoline hydrogenation catalyst is mainly used to hydrolyze olefins while removing sulfur, nitrogen, and other impurities in the pyrolysis gasoline to provide qualified raw materials for extracting aromatic hydrocarbons. This achievement has been successfully applied to the 500,000 tons/year pyrolysis gasoline second stage hydrogenation unit of Fujian United Petrochemical Company.
High space velocity/high selectivity propylene oxidation to acrolein catalyst LY-9601 can be used in the process of propylene oxidation to acrolein, the conversion of propylene is over 98.0%; the new acrolein oxidation to acrylic acid catalyst LY-9602 can be used to prepare acrylic acid by two-step oxidation of propylene. It is a commonly used technical route and the acrolein conversion rate exceeds 98.5%. Both of these catalysts can replace imported products.
According to reports, since 2007, CNPC has established an identification system for important products for independent innovation, which mainly recognizes the achievements of major scientific and technological breakthroughs, and breakthroughs in major engineering and technological bottlenecks.
Mono Calcium Phosphate ,the chemical formula is Ca (H2PO4)2.H2O, molecular weight of the body is 252.06, after dryed the product is white or slightly yellow micro powder or granules, the relative density of 2.22 (16 °C). Slightly hygroscopic, soluble in hydrochloric acid, nitric acid, slightly soluble in cold water, almost insoluble in ethanol. At 30 °C, 100 ml of water soluble MCP 1.8g. The aqueous solution was acidic, heating the aqueous solution can get calcium hydrogen phosphate. Lose crystal water at 109 °C and decomposed into calcium metaphosphate at 203°C. Applications:Monocalcium Phosphate is used to supply mineral nutrition such as phosphorus (P) and calcium (Ca) for animal, which can be easily digested and absorbed. Extensively applied as additives of Phosphorous and Calcium in aquatic animals feed.Higher water solubility of MCP is required in aquatic animals feed.
