Description

General description

EMSURE grade solvents are suitable for a broad spectrum of classical lab applications, and are frequently used in regulated and highly demanding lab applications. EMSURE provides worldwide best and most extensive product specifications. We declare our EMSURE range to be in compliance with the ACS, with the reagent part of the European Pharmacopoeia (Reag. Ph Eur) and also with the ISO standards.

Application

• Catalytic Cracking to Light Olefins: n-Pentane is extensively used in studies focused on catalytic cracking processes. Recent research has explored the use of extra-framework aluminum in ZSM-5 zeolites to enhance the production of light olefins from n-pentane. This application is crucial for improving the efficiency of catalytic processes and the production of valuable petrochemical feedstocks (He et al., Journal of Analytical and Applied Pyrolysis, 2022).
