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 ...
Stability of a Rh/CeO2–ZrO2 Catalyst in the Oxidative Steam Reforming of Raw Bio-oil
(ACS, 2018-02-21)
The oxidative steam reforming (OSR) of raw bio-oil (obtained by fast pyrolysis of pine sawdust) has been studied on a Rh/CeO2-ZrO2 catalyst under a wide range of operating conditions (600-750 ºC; steam to carbon molar ratio ...
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 ...
