Nature and Location of Carbonaceous Species in a Composite HZSM-5 Zeolite Catalyst during the Conversion of Dimethyl Ether into Light Olefins
(MDPI, 2017-09)
The deactivation of a composite catalyst based on HZSM-5 zeolite (agglomerated in a matrix using boehmite as a binder) has been studied during the transformation of dimethyl ether into light olefins. The location of the ...
A comparative thermodynamic study on the CO2 conversion in the synthesis of methanol and of DME
(Elsevier, 2017-02-01)
A thermodynamic approach of the synthesis processes of methanol and DME from H2+CO+CO2 has been conducted, in order to compare the feasibility of incorporating CO2 in the feed of both processes. The effects of reaction ...
Comparison of Ni based and Rh based catalysts performance in the oxidative steam reforming of raw bio-oil
(ACS, 2017-06-17)
The effect of O2 content in the oxidative steam reforming (OSR) of raw bio-oil has been studied, and the kinetic behavior, particularly deactivation, has been compared between two catalyst (Ni/La2O3-αAl2O3 and Rh/CeO2-ZrO2). ...
Hydrogen-rich gas production by continuous pyrolysis and in-line catalytic reforming of pine wood waste and HDPE mixtures
(Elsevier, 2017-01-12)
The continuous pyrolysis-reforming of pine sawdust and high density polyethylene mixtures (25, 50 and
75 wt% HDPE) has been performed in a two-stage reaction system provided with a conical spouted bed
reactor (CSBR) and ...
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
(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 ...
Role of operating conditions in the catalyst deactivation in the in-line steam reforming of volatiles from biomass fast pyrolysis
(Elsevier, 2017-12-09)
The effect of reforming conditions (temperature, space time and steam/biomass ratio (S/B)) has been studied in the continuous biomass pyrolysis and in-line catalytic steam reforming process in order to establish suitable ...
