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 ...
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 ...
Thermodynamic assessment of the oxidative steam reforming of biomass fast pyrolysis volatiles
(Elsevier B.V, 2020-04-30)
[EN] The joint process of pyrolysis-steam reforming is a novel and promising strategy for hydrogen production from biomass; however, it is conditioned by the endothermicity of the reforming reaction and the fast catalyst ...
Assessment of product yields and catalyst deactivation in fixed and fluidized bed reactors in the steam reforming of biomass pyrolysis volatiles
(Elsevier, 2020-08-02)
[EN] The performance of fixed and fluidized bed reactors in the steam reforming of biomass fast pyrolysis volatiles was compared, with especial attention paying to the differences observed in catalysts deactivation. The ...
Catalytic steam reforming of biomass fast pyrolysis volatiles over Ni-Co bimetallic catalysts
(Elsevier, 2020-08-11)
[EN] The influence of the metal selected as catalytic active phase in the two-step biomass pyrolysis-catalytic reforming strategy has been analyzed. The pyrolysis step was carried out in a conical spouted bed reactor at ...
Waste tyre valorization by catalytic pyrolysis – A review
(Elsevier, 2020-06-05)
[EN] The environmental concern associated with waste tyre disposal and the necessity of sustainable waste management policies has promoted the development of waste tyre valorization processes in the last decades. Within ...
Experimental study and modeling of biomass char gasification kinetics in a novel thermogravimetric flow reactor
(Elsevier B.V., 2020-04-25)
[EN]This work pursues the validation of a new reactor for the evaluation of char gasification kinetics. This novel reactor allows continuous gas flow through the fixed bed sample and accurately monitoring the mass loss ...
Pyrolysis of plastic wastes in a fountain confined conical spouted bed reactor: determination of stable operating conditions
(Elsevier, 2020-12-31)
[EN] The performance of both fluidized and spouted bed reactors in the pyrolysis of waste plastics is conditioned by particle agglomeration phenomena, which worsen the quality of the gas-solid contact and eventually lead ...
Deactivation of Ni spinel derived catalyst during the oxidative steam reforming of raw bio-oil
(Elsevier, 2020-05-12)
Deactivation of a bulk catalyst derived from NiAl2O4 spinel during the oxidative steam reforming (OSR) of raw bio-oil has been studied. The experiments were performed in a continuous system with two units in series: a ...
Co-cracking of high-density polyethylene (HDPE) and vacuum gasoil (VGO) under refinery conditions
(Elsevier B.V., 2020-02)
The co–cracking of a 5 wt% of high–density polyethylene (HDPE) dissolved in vacuum gasoil (VGO) under conditions similar to those of the industrial fluid catalytic cracking (FCC) unit has been studied. The main goal has ...
