Analysis and Economic Evaluation of the Use of Recycled Polyamide Powder in Masonry Mortars
(MDPI, 2020-11-11)
Due to the considerable amount of waste plastics and polymers that are produced annually, the introduction of these waste products in construction materials is becoming a recurrent solution to recycle them. Among polymers, ...
CFD modeling and experimental validation of biomass fast pyrolysis in a conical spouted bed reactor
(Elsevier, 2020-12-31)
[EN] A 2D Euler-Euler multiphase computational fluid dynamics (CFD) model in conjunction with the kinetic theory of granular flow (KTGF) was applied to describe the biomass pyrolysis in a spouted bed reactor. The primary ...
Pyrolysis of plastic wastes in a fountain confined conical spouted bed reactor: determination of stable operating conditions
(Elsevier, 2020-12-31)
[EN] The performance of both fluidized and spouted bed reactors in the pyrolysis of waste plastics is conditioned by particle agglomeration phenomena, which worsen the quality of the gas-solid contact and eventually lead ...
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 ...
Golgi Oncoprotein GOLPH3 Gene Expression is Regulated by Functional E2F and CREB/ATF Promoter Elements
(MDPI, 2019-03-25)
The Golgi organelle duplicates its protein and lipid content to segregate evenly between two daughter cells after mitosis. However, how Golgi biogenesis is regulated during interphase remains largely unknown. Here we show ...
Cobalt aluminate spinel-derived catalysts for glycerol aqueous phase reforming
(Elsevier, 2018-08-02)
Catalytic activity at mild (235 °C/3.5 MPa) and severe (260 °C/5.0 MPa) APR conditions was investigated over catalysts based on cobalt aluminate spinel synthetized by coprecipitation. Co/Al ratio was varied and physicochemical ...
Nickel aluminate spinel-derived catalysts for the aqueous phase reforming of glycerol: Effect of reduction temperature
(Elsevier B.V., 2018-12-07)
Bulk nickel aluminate (NiAl2O4) was synthesised by co-precipitation at a Ni/Al mole ratio of 1:2 (stoichiometric ratio). The prepared sample was reduced at different temperatures, in the 300 to 850 ºC range, and obtained ...
Oxidation of residual methane from VNG vehicles over Co3O4-based catalysts: Comparison among bulk, Al2O3-supported and Ce-doped catalysts
(Elsevier, 2018-06-20)
Cobalt oxide based catalysts with three different active phase configurations, namely bulk, alumina supported and cerium-doped Co3O4 samples were examined for the complete oxidation of methane under conditions similar to ...
Optimisation of bimetallic Co-Ni supported catalysts for oxidation of methane in natural gas vehicles
(Elsevier, 2020-11-21)
This work deals with the extensive study of supported bimetallic Co-Ni catalysts for the complete oxidation of methane. The simultaneous incorporation of nickel and cobalt was found to enhance the redox properties by ...
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 ...
