Deactivation of Ni spinel derived catalyst during the oxidative steam reforming of raw bio-oil
Arandia Gutiérrez, Aitor; Remiro Eguskiza, Aingeru; Oar Arteta, Lide; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (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 ... -
Hidrogeno-ekoizpena bio-oilaren erreformatze katalitikoaren bidez
Remiro Eguskiza, Aingeru; Oar Arteta, Lide; Gayubo Cazorla, Ana Guadalupe (Servicio Editorial de la Universidad del País Vasco/Euskal Herriko Unibertsitatearen Argitalpen Zerbitzua, 2017)The growing demand of H2 for its use as petrochemical raw material and clean fuel has boosted the development of processes for its production from alternative sources to oil, among which biomass has received special attention ... -
Hydrogen production by steam reforming of bio-oil/bio-ethanol mixtures in a continuous thermal-catalytic process
Remiro Eguskiza, Aingeru; Valle Pascual, Beatriz; Oar Arteta, Lide; Aguayo Urquijo, Andrés Tomás; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (Elsevier, 2014-04-24)
The feasibility of the steam reforming of bio-oil aqueous fraction and bio-ethanol mixtures has been studied in a continuous process with two in-line steps: thermal step at 300 ºC (for the controlled deposition of pyrolytic ... -
Origin and nature of coke in ethanol steam reforming and its role in deactivation of Ni/La2O3-αAl2O3 catalyst
Montero, Carolina; Remiro Eguskiza, Aingeru; Valle Pascual, Beatriz; Oar Arteta, Lide; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (ACS, 2019-07-22)Deactivation of Ni/La2O3-αAl2O3 catalyst in the ethanol steam reforming (ESR) was studied in order to establish the optimal conditions for maximizing H2 production and achieving a steady behaviour. The ESR reactions were ... -
Reaction conditions effect and pathways in the oxidative steam reforming of raw bio-oil on a Rh/CeO2-ZrO2 catalyst in a fluidized bed reactor
Arandia Gutiérrez, Aitor; Remiro Eguskiza, Aingeru; Oar Arteta, Lide; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (Elsevier, 2017-12-07)A reaction scheme has been proposed for the oxidative steam reforming (OSR) of raw bio-oil on a Rh/CeO2-ZrO2 catalyst, based on the study of the effect reaction conditions (temperature, space time, oxygen/carbon ratio and ... -
Regeneration of NiAl2O4 spinel type catalysts used in the reforming of raw bio-oil
Remiro Eguskiza, Aingeru; Arandia Gutiérrez, Aitor; Oar Arteta, Lide; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (Elsevier, 2018-12-01)The regenerability of Ni catalysts in reforming reactions is a key factor for process viability. Accordingly, this study addresses the regeneration of two spinel NiAl2O4 type catalysts by reaction-regeneration cycles in ... -
