Preparative HPLC with ultrastable-Y zeolite for compound-speci®c carbon isotopic analyses
Preparative high pressure liquid chromatography on US-Y zeolite shape-selective molecular sieve was studied for carbon isotopic fractionation eects. We tested a standard mixture [17b, 21b(H)-hopane, 5a-cholestane] and complex natural hydrocarbon mixtures dominated by tetraand pentacyclic triterpenoids extracted from Oxford Clay shales. We con®rmed that steroids and hopanoids were separated on ...
متن کاملSynthesis and Catalytic Performance of Large Zeolite Y Crystals
1. Introduction Zeolites have gained an irreplaceable role as catalysts in the refining industry. With a production capacity of 625·10 6 t in 2004, the fluid catalytic cracking process (FCC) represents the second most important heterogeneously catalyzed process [1]. As an active component, the catalyst of this process contains zeolite H-Y. Since a high-molecular feed is used, a detailed knowled...
متن کاملImproving CO2 adsorption with new amine-functionalized Y-type zeolite
In this work, a new synthesized Y-type zeolite with an Si/Al molar ratio of 2.5 (NaY) was modified with amines, in order to probe the influence of the modification of the adsorbent’s surface on CO2 adsorption. The three selected amines were diethanolamine, tetraethylenepentamine, and 2- methylaminoethanol. The surface nature of NaY was changed after amine modification, which causes a...

Pyrolysis of latex gloves in the presence of Y-zeolite.
In this study we have investigated the possibility of processing waste rubber gloves using pyrolysis. Y-zeolite catalyst was employed to upgrade the pyrolysis products to give higher yields of valuable aromatic compounds such as toluene and xylenes. The composition of the pyrolysis products was determined using gas chromatography with linked mass spectrometry (GC-MS), gas chromatograph equipped...
