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 ...
Catalytic removal of chlorinated compounds over ordered mesoporous cobalt oxides synthesised by hard-templating
(Elsevier, 2017-09-28)
This work evaluates the catalytic behaviour of a series of mesoporous bulk cobalt oxide prepared by hard-templating using SBA-15, SBA-16 and SBA-3. In addition, a bulk catalyst obtained by silica aquagel confined precipitation ...
Pd supported catalyst for gas-phase 1,2-dichloroethane abatement: Efficiency and high selectivity towards oxygenated products
(Elsevier, 2017-08-12)
Hydroxyapatite (HAP) support has been synthesised and impregnated with different amounts of Pd. The prepared Pd/HAP catalysts have been thoroughly characterised by BET, XRD, TEM, UV–visible–NIR, FTIR, XPS, CO2-TPD and NH ...
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). ...
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 ...
Upgrading of sewage sludge by demineralization and physical activation with CO2: Application for methylene blue and phenol removal
(2017-09)
Carbon-based adsorbents were prepared by the physical activation of sewage sludge with CO2 through an integrated method (without a precarbonization stage). The activation was conducted at different temperatures (600e1000 ...
