Changchun desulfurization catalyst manufacturer Dongshi DXY series catalysts for selective catalytic oxidation

  Since 2012, Changchun Dongshi company has invested considerable human and material resources to research and develop a new process technology for removing hydrogen sulfide from gas in cooperation with relevant universities and research institutions
That is, a new process technology for removing H2S by one-step catalytic conversion of sulfur-containing gas, which is abbreviated as & ldquo; DXY New Desulfurization Technology & rdquo;
DXY desulfurization is a new desulfurization technology in which a certain amount of O2 is added into the sulfur-containing gas, the H2S in the gas is directly oxidized to elemental sulfur by O2 under the action of catalyst, and then the elemental sulfur is separated from the gas by using a special sulfur capture device, so as to achieve the purpose of removing H2S
Changchun Dongshi company has successfully developed a special catalyst dxy-1 for the catalytic conversion of acid gas H2S by using the mode of combination of production, learning and research, and according to the process of laboratory formula screening, pilot test, factory side line test or industrial test Dxy-2 special catalyst for H2S catalytic conversion of shift gas and dxy-3 special catalyst for H2S catalytic conversion of methane gas (biogas)

Main technical parameters of dxy-1 selective catalytic catalyst: (applicable to gas source: conversion of H2S in acid analytical gas and H2S in CO2) physical properties ① physical and chemical properties of the catalyst are strip , 5× （5-15）mm； ② The specific surface area is greater than 100m2 / g; ③ The pore volume is greater than or equal to 0
2ml/g; ④ The average crushing strength is greater than 80N / piece; ⑤ Bulk density: 0
95 ~ 1
05kg/l; ⑥ The wear rate is less than 1
