- VTRAC催化助劑 -

產(chǎn)品特點

VTRAC作為助劑應(yīng)用于催化裂化裝置中,可與催化劑一起注入再生器中,簡單方便,加入量占系統(tǒng)藏量5%-10%。

VTRAC由活性組分和載體制成,其活性組分為復(fù)合金屬氧化物,載體為孔徑梯度分布的硅鋁材料,兩者協(xié)同作用可有效提高其金屬捕集能力。在催化裂化工藝過程中,重金屬被其活性組分捕獲并反應(yīng),生成惰性的無害化合物或合金,保護催化劑維持原有的活性和選擇性。

具有以下特點:

1、捕集金屬釩和抗重金屬能力強,捕釩系數(shù)>10;

2、降低裝置內(nèi)焦炭和氫氣產(chǎn)率;

3、優(yōu)良的耐磨性能,不會對裝置流化、運轉(zhuǎn)產(chǎn)生不良影響。
