Investigation of Massive Catalyst based on Molybdenum Disulphide by Simultaneous Thermal Analysis and Mass Spectrometry Methods [PDF]
, 2015 The paper presents the results of experimental studies of massive sulfide catalysts by simultaneous thermal analysis and mass spectrometry. It is found that the STA/MS methods are quite informative for testing the catalyst systems based on MoS2 and are ...

Engineering Ni–Mo–S Nanoparticles for Hydrodesulfurization [PDF]
Nano Letters, 2018 Nanoparticle engineering for catalytic applications requires both a synthesis technique for the production of well-defined nanoparticles and measurements of their catalytic performance. In this paper, we present a new approach to rationally engineering highly active Ni-Mo-S nanoparticle catalysts for hydrodesulfurization (HDS), i.e., the removal of ...

AIChE Journal, Volume 72, Issue 2, February 2026.Abstract Olefin extractive separation from fluid catalytic cracking (FCC) naphtha with deep eutectic solvents (DESs) was systematically investigated in this work. In a first step, different DESs were screened for their separation performance of the binary mixture benzene/1‐hexene.

ChemCatChem, Volume 18, Issue 1, 15 January 2026.Rounded TiO2 nanoparticles we sucesfully synthesized with modulated sizes from 109 to 22 nm. We observed the WS2 and NiWS active phases forming parallel slabs to the surface. The presence of Ni helped W to be better dispersed, especially on the smallest nanoparticles, which resulted in the highest activity detected among the series.
