This talk high\u00adlights the syn\u00adthe\u00adsis and cat\u00adalyt\u00adic char\u00adac\u00adter\u00adi\u00adza\u00adtions of three emerg\u00ading acidic meso-\/mi\u00adcro-porous lamel\u00adlar zeo\u00adlite mate\u00adri\u00adals (self-pil\u00adlared MFI, pil\u00adlared MFI, mul\u00adti\u00adl\u00adamel\u00adlar MFI), with a focus on their cat\u00adalyt\u00adic behav\u00adior inves\u00adti\u00adga\u00adtions using ethanol dehy\u00addra\u00adtion, monomol\u00ade\u00adc\u00adu\u00adlar con\u00adver\u00adsion of propane and isobu\u00adtane, and alky\u00adla\u00adtion of mesity\u00adlene with ben\u00adzyl alco\u00adhol as probe reac\u00adtions. The rate and appar\u00adent acti\u00adva\u00adtion ener\u00adgy of the cat\u00adalyt\u00adic ethanol and small alka\u00adne probe reac\u00adtions in zeo\u00adlites pos\u00adsess\u00ading dual micro- and meso-poros\u00adi\u00adty was com\u00adpa\u00adra\u00adble to con\u00adven\u00adtion\u00adal micro\u00adp\u00adorous MFI mate\u00adri\u00adals, imply\u00ading that the cat\u00adalyt\u00adic behav\u00adior of Br\u00f8n\u00adst\u00aded acid sites in mate\u00adri\u00adals with dual meso-\/mi\u00adcro-poros\u00adi\u00adty is pref\u00ader\u00aden\u00adtial\u00adly dom\u00adi\u00adnat\u00aded by the micro\u00adp\u00adorous envi\u00adron\u00adment pos\u00adsi\u00adbly because it pro\u00advides a bet\u00adter fit for adsorp\u00adtion of small alka\u00adne or alco\u00adhol reac\u00adtant mol\u00ade\u00adcules.

A math\u00ade\u00admat\u00adi\u00adcal mod\u00adel accounts for the exter\u00adnal reac\u00adtion, inter\u00adnal reac\u00adtion, and dif\u00adfu\u00adsion devel\u00adoped to under\u00adstand the cat\u00adalyt\u00adic behav\u00adiors of these cat\u00ada\u00adlysts.
