Abstract

Abstract: Adsorption and diffusion behavior of aromatic hydrocarbons (benzene, pxylene and cumene) on Fluid Catalytic Cracking (FCC) catalysts and multisites of components REUSY zeolite have been systematically investigated by N2 adsorption, Intelligent Gravimetric Analyser (IGA) and Temperature Programmed Desorption (TPD) technology. Only one adsorption model for aromatic hydrocarbons in FCC catalysts and REUSY zeolite was observed in TG/DTG profiles, speculating that the adsorption mode was π electron interactions between aromatic and adsorbent. The controlling steps for the overall mass transfer process in the FCC catalyst particles are the diffusion process in the length scale of macropore of the matrix or/and the mass transfer at the zeolitematrix interface rather than the intracrystalline diffusion one in the micropores of the zeolite crystals.

摘要： 利用智能重量分析仪( I GA) 和程序升温脱附技术( T P D) 研究芳烃( 苯、对二甲苯及异丙苯) 在流化催化裂化( F C C) 催化剂及稀土超稳 Y型分子筛上的吸附扩散行为。TG / DTG曲线表明, 芳烃在F C C催化剂及稀土超稳Y型分子筛上只存在一种吸附模式, 推测这种吸附模式是芳烃与吸附剂之间通过π电子相互作用。另外, F C C催化剂颗粒中, 整个传质过程中的速控步骤不是 Y型分子筛晶粒内微孔孔道中的扩散过程, 而是催化剂基质中长程的大/介孔内的扩散过程及分子筛微孔与基质界面之间的分子交换过程。
