Operating conditions for attenuating Ni/La2O3-αAl2O3 catalyst deactivation in the steam reforming of bio-oil aqueous fraction
(Elsevier, 2013-07-16)
A study was carried out on the effect of temperature (in the 500–800 °C range) and space–time (between 0.10 and 0.45 gcatalyst h(gbio-oil)− 1) on Ni/La2O3–αAl2O3 catalyst deactivation by coke deposition in the steam reforming ...
Model validation of a packed bed LTA membrane reactor for the direct synthesis of DME from CO/CO2
(2020-10-16)
A model for simulating the direct synthesis of dimethyl ether (DME) in a packed bed membrane reactor (PBMR) has been validated, using a LTA zeolite hydrophilic membrane in a lab-scale reaction equipment. In the model, ...
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 ...
Steam reforming of the bio-oil aqueous fraction in a fluidized bed reactor with in situ CO2 capture
(ACS, 2013-11-11)
The effect of CO2 capture in the hydrogen production by steam reforming of the bio-oil aqueous fraction was studied. The reforming and cracking activity of the adsorbent (dolomite) and relationship between these reactions ...
Stability of CuZnOAl2O3/HZSM-5 and CuFe2O4/HZSM-5 catalysts in dimethyl ether steam reforming operating in reaction-regeneration cycles
(Elsevier, 2014-05-21)
The study focuses on the regenerability of bifunctional catalysts prepared with different metallic functions (CuZnOAl2O3 and CuFe2O4 spinel) and HZSM-5 zeolite (SiO2/Al2O3 = 30) as the acid function. These catalysts have ...
Steam reforming of raw bio-oil in a fluidized bed reactor with prior separation of pyrolytic lignin
(ACS, 2013-11-11)
The effect operating conditions (temperature, steam/carbon molar ratio and space-velocity) have on the steam reforming of raw bio-oil has been studied in a two-step reaction unit. In the first step (operated at 500 ºC), a ...
