MYI-2001型催化裂化催化劑水蒸汽老化裝置
催化劑的老化失活是研究催化劑反應(yīng)的一個(gè)重要問題。影響催化劑失活的原因是催化劑在工藝裝置中處于存在水蒸汽氣氛的高溫環(huán)境中，使催化劑原始粒子結(jié)構(gòu)的排列改變，以致表面積變小，孔分布變粗。該催化劑水蒸汽老化裝置是在一定溫度、分壓、空速、處理時(shí)間條件下，對(duì)催化劑進(jìn)行老化處理的實(shí)驗(yàn)室裝置，從試驗(yàn)可得到與工業(yè)平衡劑某些性能和結(jié)構(gòu)相似的結(jié)果。
Catalytic cracking catalyst vapour ageing unit:
The ageing deactivation of the catalyst is a important problem to research catalyst reaction.The reason that affects the catalyst activation ys that the high temperature of the aqueous vpour changes the stercture and order of the molecules,so the surface area of the catalyst is decreased and the pore distribution ys more broad .This unit is a laboratory device to age the fractiona pressure ,the space velocity ,and the dealing time .Theresult of the test is similar with the properties and structures of equilibrium reagents.
