Implications of Co-Feeding Water on the Growth Mechanisms of Retained Species on a SAPO-18 Catalyst during the Methanol-to-Olefins Reaction
(Wiley, 2021-07-07)
The dynamics of retained and deactivating species in a SAPO-18 catalyst during the methanol-to-olefins reaction have been followed using a combination of ex-situ and in-situ techniques in differential and integral reactors.The ...
Dynamics of carbon formation during the catalytic hydrodeoxygenation of raw bio-oil
(Royal Society of Chemistry, 2020-11-01)
The formation, growth and transformation of the carbon residue (coke) deposited on the catalyst during the raw bio-oil hydrodeoxygenation have been studied. These deposits have a great impact on the overall process ...
Nature and Location of Carbonaceous Species in a Composite HZSM-5 Zeolite Catalyst during the Conversion of Dimethyl Ether into Light Olefins
(MDPI, 2017-09)
The deactivation of a composite catalyst based on HZSM-5 zeolite (agglomerated in a matrix using boehmite as a binder) has been studied during the transformation of dimethyl ether into light olefins. The location of the ...
Oxidative Steam Reforming of Raw Bio-Oil over Supported and Bulk Ni Catalysts for Hydrogen Production
(MDPI, 2018-08)
Several Ni catalysts of supported (on La2O3-alpha Al2O3, CeO2, and CeO2-ZrO2) or bulk types (Ni-La perovskites and NiAl2O4 spinel) have been tested in the oxidative steam reforming (OSR) of raw bio-oil, and special attention ...
Special Issue on Catalyst Deactivation and Regeneration
(MDPI, 2021-06-30)
Catalyst deactivation causes major losses in the chemical industry worldwide every year [...]
Thermochemical CO2 reduction catalyzed by homometallic and heterometallic nanoparticles generated from the thermolysis o supramolecularly assembled porous metal-adenine precursors
(American Chemical Society, 2023-10-09)
A family of unprecedented supramolecularly assembled porous metal–organic compounds (SMOFs), based on [Cu6M(μ-adeninato)6(μ3-OH)6(μ-H2O)6]2+ cations (MII: Cu, Co, Ni, and Zn) and different dicarboxylate anions (fumarate, ...
A straightforward route to obtain zirconium based metal-organic gel
(Elsevier, 2019-04-12)
Zirconium based metal-organic gels are obtained through a rapid method at room temperature, employing green solvents, in which the role of water is important. These porous materials, decorated with Brønsted acid sites, ...
A Data-Driven Reaction Network for the Fluid Catalytic Cracking of Waste Feeds
(MDPI, 2018-11-27)
Establishing a reaction network is of uttermost importance in complex catalytic processes such as fluid catalytic cracking (FCC). This step is the seed for a faithful reactor modeling and the subsequent catalyst re-design, ...
Coking and sintering progress of a Ni supported catalyst in the steam reforming of biomass pyrolysis volatiles
(Elsevier, 2018-10)
The valorization of biomass (pine wood) for hydrogen production has been studied in a
two-step process, comprising pyrolysis and subsequent steam reforming of the volatiles
produced in the first step. This work focuses ...
Coke deposition and product distribution in the co-cracking of waste polyolefin derived streams and vacuum gas oil under FCC unit conditions
(Elsevier, 2019-09)
The effect of co-cracking of high-density polyethylene (HDPE) or its pyrolysis wax together with vacuum gasoil (VGO) has been studied. The aim is to determine the content, nature, and location of coke while analyzing the ...
