A Hybrid FCC/HZSM-5 Catalyst for the Catalytic Cracking of a VGO/Bio-Oil Blend in FCC Conditions
(MDPI, 2020)
The performance of a commercial FCC catalyst (designated as CY) and a physically mixed hybrid catalyst (80 wt.% CY and 20 wt.% HZSM-5-based catalyst, designated as CH) have been compared in the catalytic cracking of a ...
Investigation of hot char catalytic role in the pyrolysis of waste tires in a two-step process
(Elsevier, 2019-12-30)
[EN] This study pursues the valorization of waste tires by pyrolysis using a different approach for tire parts, specifically, the tire tread rubber and side wall rubber. Tire tread rubber was used to produce hot char with ...
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 ...
Insights into the Reaction Routes for H2 Formation in the Ethanol Steam Reforming on a Catalyst Derived from NiAl2O4 Spinel
(American Chemical Society, 2021-11-04)
[EN]This work describes the satisfactory performance of a Ni/Al2O3 catalyst derived from NiAl2O4 spinel in ethanol steam reforming and focuses on studying the prevailing reaction routes for H-2 formation in this system. ...
Stability of a NiAl2O4 Derived Catalyst in the Ethanol Steam Reforming in Reaction-Regeneration Cycles: Effect of Reduction Temperature
(MDPI, 2022-05-17)
The catalyst regeneration is still a challenge to make the ethanol steam reforming (ESR) process feasible for sustainable H2 production. NiAl2O4 spinel derived catalysts are highly active and selective for ESR, but they ...
CeO2 and La2O3 promoters in the steam reforming of polyolefinic waste plastic pyrolysis volatiles on Ni-based catalysts
(American Chemical Society, 2020-11-09)
[EN] Based on the promising results of La2O3 and CeO2 promoted Ni/Al2O3 catalysts in the reforming
of biomass pyrolysis volatiles, the performance of these catalysts and the non-promoted one was
2 evaluated in the pyrolysis ...
Activity and stability of different Fe loaded primary catalysts for tar elimination
(Elsevier, 2022-06)
[EN] The performance of olivine, dolomite and gamma-alumina primary catalysts was evaluated in the continuous tar elimination process in which toluene was selected as the biomass gasification tar model compound. Iron was ...
Progress on Catalyst Development for the Steam Reforming of Biomass and Waste Plastics Pyrolysis Volatiles: A Review
(American Chemical Society, 2021-11-04)
[EN]n recent decades, the production of H-2 from biomass, waste plastics, and their mixtures has attracted increasing attention in the literature in order to overcome the environmental problems associated with global warming ...
Analysis of hydrogen production potential from waste plastics by pyrolysis and in line oxidative steam reforming
(Elsevier, 2022-01)
[EN] A study was carried out on the valorization of different waste plastics (HDPE, PP, PS and PE), their mixtures and biomass/HDPE mixtures by means of pyrolysis and in line oxidative steam reforming. A thermodynamic ...
Sorption enhanced ethanol steam reforming on a bifunctional Ni/CaO catalyst for H-2 production
(Elsevier, 2021-12)
[EN]The activity and stability of a 10 wt%NiO/CaO catalyst were tested in the sorption enhanced ethanol steam reforming (SEESR) in a fluidized bed reactor. The effect of temperature in the 600-750 degrees C range was ...
