Effect of La2O3 promotion on a Ni/Al2O3 catalyst for H2 production in the inline biomass pyrolysis-reforming
(Elsevier B.V., 2019-11-19)
[EN] The effect of La2O3 addition on a Ni/Al2O3 catalyst has been studied in the biomass pyrolysis and in-line catalytic steam reforming process. The results obtained using homemade catalysts (Ni/Al2O3 and Ni/La2O3-Al2O3) ...
Effect of CeO2 and MgO promoters on the performance of a Ni/Al2O3 catalyst in the steam reforming of biomass pyrolysis volatiles
(Elsevier B.V., 2019-10-25)
A Ni/Al2O3 catalyst has been modified incorporating CeO2 and MgO promoters in order to improve its performance in the steam reforming of biomass pyrolysis volatiles. Ni/Al2O3, Ni/CeO2-Al2O3 and Ni/MgO-Al2O3 catalysts have ...
Influence of reactor and condensation system design on tyre pyrolysis products yields
(Elsevier B.V., 2019-09-07)
This study investigates the effect the pyrolysis reactor and the condensing system type have on the tyre derived oil (TDO) and DL-limonene yield, as well as benzothiazole concentration in the TDO. All the experiments were ...
Cost-effective upgrading of biomass pyrolysis oil using activated dolomite as a basic catalyst
(Elsevier B.V., 2019-07-19)
This study deals with a continuous process on a calcined dolomite operating at atmospheric pressure and by cofeeding
water for cost-effective upgrading of raw bio-oil at 400 °C and 500 °C. The distribution of carbon in ...
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 ...
Assessing the potential of the recycled plastic slow pyrolysis for the production of streams attractive for refineries
(Elsevier, 2019-07-25)
The slow pyrolysis of recycled high-density polyethylene (HDPE) has been investigated in a batch autoclave reactor at 430–490 °C and reaction times of 15–60 min, with the aim of obtaining the maximum yield of plastic oil ...

(Elsevier, 2019-05-22)
[ES] Se ha desarrollado y validado una metodología basada en la técnica boroscópica para seguir el movimiento del sólido dentro de un reactor spouted bed cónico. El procedimiento desarrollado y perfeccionado permite ...
On the dynamics and reversibility of the deactivation of a Rh/CeO2-ZrO2 catalyst in raw bio-oil steam reforming
(Elsevier, 2019-01-28)
The deactivation mechanism of a commercial Rh/CeO2-ZrO2 catalyst in raw bio-oil steam reforming has been studied by relating the evolution with time on stream of the bio-oil conversion and products yields and the physicochemical ...
Origin and nature of coke in ethanol steam reforming and its role in deactivation of Ni/La2O3-αAl2O3 catalyst
(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 ...
Strategies for the intensification of CO2 valorization in the one-step dimethyl ether synthesis process
(ACS, 2019-12-16)
The intensification of CO2 valorization has been theoretically studied in the direct synthesis of dimethyl ether (DME) carried out in a packed-bed reactor by means of two strategies pursuing the attenuation of the thermodynamic ...
