低温变换催化剂 Low Temperature Shift Catalyst
1. 产品简介 Product Introduction
低温变换催化剂(HHTS01型)适用于天然气、焦炉气、炼厂气、石脑油、煤、油田气等不同原料的制氢、制氨工艺中低含量CO的变换反应。本催化剂充分借鉴了国内生产低变催化剂的经验,产品性能更为稳定,催化剂单位体积内铜含量较高,分散度好,有效铜表面积较大、活性稳定性好,强度和抗毒性能也得到了有效的改善。HHB01烧失重低、体积收缩率低、孔容大、比重和孔径适宜、易于还原。经各用户使用,低变出口CO通常能达到接近0.1%的水平。其各项性能经测试和实际使用表明,本催化剂已处于国际同类产品的先进水平。该催化剂不仅适用于轴向变换炉,也适用于轴径向变换炉。
HHTS01 low temperature shift catalyst is used to produce hydrogen and ammonia which use natural gas, coke-oven gas, refinery gas, naphtha, coal and oil field gas as raw material.
Advantages:
a) Steady product performance with uniform density of Gu content, large effective surface area.
b) Outstanding activity, crushing strength and mithridatism.
c) Outstanding physical characteristic.
d) CO content less than 0.1% after conversion.
e) Both axial converter and axial radial converter are available to apply.
