Methanol-to-hydrocarbon (MTH) processes over H-ZSM-5 zeolites: New kinetic modeling methodology using forced periodic operation and improvements in catalyst formulation
(2023-05-22)
This Thesis focuses on the implementation of novel catalyst formulations selective towards aromatics and innovative reactor operation methodologies towards the development of a unified kinetic model for Methanol-to-hydrocarbon ...
Catalytic pathwayz and deactivation in alternative sources of fuel production: butene oligomerizaton and ship/shale-gasoils cracking
(2023-04-20)
Catalytic pathways and deactivation on acid catalysts have been studied for two industrial catalytic processes implemented in the current refinery, oligomerization and FCC units, which are versatile for facing the recent ...
Fuel production by hydrocracking of non-olefinic plastics and vacuum gasoil blends
(2023-05-05)
The catalytic hydrocracking of different blends of non-olefinic polymers (polystyrene, polymethylmethacrylate and polyethylene terephthalate) with vacuum gasoil has been studied to produce fuel streams suitable for inclusion ...

(2019-12-10)
La tecnología de los condensadores de metal ion (MIC, siendo M = L para Li y N para Na) se desarrolló por primera vez a principios de los años 2000 como un enfoque novedoso basado en la hibridación interna de baterías de ...
Co-hydrocracking of polyolefinic waste plastic with an intermediate stream of refinery
(2021-01-21)
This thesis is focused in hydrotreating and hydrocracking secondary refinery streams that have been previously hydrotreated (drastically reducing their heteroatom content) for their valorization both, alone and co-processed ...
Experimental development and modeling of a membrane reactor for the direct synthesis of DME with CO2 valorization.
(2019-09-27)
Se ha estudiado la síntesis directa de dimetil éter (DME) a partir de sistemas H2+CO+CO2, con un reactor de membrana de lecho fijo (PBMR). El trabajo experimental para el diseño y puesta a punto del reactor ha consistido ...
Advanced technologies for the reduction of the carbon footprint in the reforming of bio-oil over NiAl2O4 derived catalyst
(2024-01-12)
This Thesis focuses on the reduction of the carbon footprint in bio-oil reforming by two alternative strategies: i) sorption enhanced steam reforming (SESR), which minimises CO2 emissions by in situ CO2 capture and enhances ...
