A process for the preparation and modification of additives, with a zeolite base and a high silica alumina ratio (SAR) like the ZSM-5, to increase the yield of propene and LPG in low severity FCC operations, that seeks to maximize the production of medium-distillates with low aromaticity and to minimize molecular cracking in the LCO range. The additives involved guarantee an increase in light olefin yields without altering the yield or the quality of the LCO produced. The innovative process includes surprising actions from rare earths (RE) on the active sites of zeolite, that at once partially block their pores and, in this way, make molecular cracking in the medium-distillate range difficult, which preferably occur at low reaction temperatures and keeps the remaining sites quite active. These sites are sufficiently active to crack smaller molecules in the gasoline range, guaranteeing an overall increase in light olefins and allowing the additive involved to be used industrially in operations to maximize medium-distillates in an FCC unit. This new additive may be obtained by modifying any commercial ZSM-5 zeolite additive.

A shotgun metabolomics approach using MALDI-tandem mass spectrometry was developed for the rapid analysis of cellular metabolites. Through the use of neutral organic solvents to inactivate endogenous enzyme activities (i.e., methanol / chloroform / H2O extraction), multiplexed extraction conditions and combinatorial alterations in matrix stereoelectronic composition and analyte interactions, multiple suites of metabolites were directly ionized and quantitated directly from biologic extracts without the need for prior chromatographic separation. Through combinatorial alterations in 9-aminoacridine charge, aromaticity and stacking, a set of multiplexed conditions was developed that allowed identification of many hundreds of peaks corresponding to metabolites from mouse heart extracts. Identification of metabolite peaks was based on mass accuracy and isomeric species were assigned based on diagnostic fragment ions present during tandem mass spectrometry for many of the identified metabolite peaks.
