José Marcos is a Chemical Engineer graduated at the Universidade Federal do Rio de Janeiro (EQ/UFRJ, 1987), with an M.Sc. in catalysis (COPPE/PEQ/UFRJ, 1991), Executive MBA (COPPEAD/UFRJ, 2003) and is presently a D.Sc. Candidate at EQ/UFRJ (defense due in 2Q 2023). He has 30+ years of experience with the Chemical Process Industry, with emphasis on the production of fluid bed catalysts (FCC), synthesis and modification of zeolites and other intermediates. He currently holds the position of FCC Technical Advisor with Fábrica Carioca de Catalisadores, leading the R&D of zeolitic catalysts for the circular economy: chemical recycling of plastics and rubber, biomass conversion into fuels and chemicals, biofuels production. He has developed and successfully introduced new technologies in the commercial production of FCC catalysts, such as a new zeolite precursor, scale-up (bench-pilot-industrial) of ZSM-5 production technology and high accessibility FCC catalysts that have increased the catalyst plant profitability.
