چکیده
This paper is a part of study on reactivity descriptors in vacuum gas oil hydrotreatment (VGO HDT). It aims to understand the differences feeds various process origins and corresponding hydrotreated effluents molecular level. Four different oils were over sulfided NiMo/Al2O3 catalyst at wide range temperatures residence times order collect HDT broad hydrodenitrogenation (HDN) conversions. Vacuum have been analyzed by Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) positive ESI(+) negative ESI(-) electrospray ionization modes characterize basic neutral nitrogen-containing species subtleties transformations depending feedstock type.

Structural Analysis of -Carrageenan Sulfated Oligosaccharides by Positive Mode Nano-ESI- FTICR-MS and MS/MS by SORI-CID
Structural analysis of sulfated oligosaccharides from -carrageenan of up to ten residues (MW 2 kDa) was successfully carried out by positive mode nano-ESI-FTICR-MS together with MS/MS using sustained off-resonance irradiation-collision induced dissociation (SORI-CID). Glycosidic bond cleavage reactions via the Band Y-types of fragmentation were observed and enabled complete sequencing of the ol...

متن کاملTopoisomer differentiation of molecular knots by FTICR MS: lessons from class II lasso peptides.
Lasso peptides constitute a class of bioactive peptides sharing a knotted structure where the C-terminal tail of the peptide is threaded through and trapped within an N-terminal macrolactam ring. The structural characterization of lasso structures and differentiation from their unthreaded topoisomers is not trivial and generally requires the use of complementary biochemical and spectroscopic me...
