Catalytic steam reforming of biomass fast pyrolysis volatiles over Ni-Co bimetallic catalysts
(Elsevier, 2020-08-11)
[EN] The influence of the metal selected as catalytic active phase in the two-step biomass pyrolysis-catalytic reforming strategy has been analyzed. The pyrolysis step was carried out in a conical spouted bed reactor at ...
Role of temperature in the biomass steam pyrolysis in a conical spouted bed reactor
(Elsevier, 2022-01-01)
[EN] The steam pyrolysis of pinewood sawdust has been conducted in a bench scale plant provided with a conical spouted bed reactor (CSBR). This process is of uttermost relevance for the in-line valorisation of pyrolysis ...
Conversion of HDPE into Value Products by Fast Pyrolysis Using FCC Spent Catalysts in a Fountain Confined Conical Spouted Bed Reactor
(Wiley, 2021-10-05)
Continuous catalytic cracking of polyethylene over a spent fluid catalytic cracking (FCC) catalyst was studied in a conical spouted bed reactor (CSBR) with fountain confiner and draft tube. The effect of temperature (475-600 ...
Waste tyre valorization by catalytic pyrolysis – A review
(Elsevier, 2020-06-05)
[EN] The environmental concern associated with waste tyre disposal and the necessity of sustainable waste management policies has promoted the development of waste tyre valorization processes in the last decades. Within ...
Influence of reactor and condensation system design on tyre pyrolysis products yields
(Elsevier B.V., 2019-09-07)
This study investigates the effect the pyrolysis reactor and the condensing system type have on the tyre derived oil (TDO) and DL-limonene yield, as well as benzothiazole concentration in the TDO. All the experiments were ...
On the pyrolysis of different microalgae species in a conical spouted bed reactor: Bio-fuel yields and characterization
(Elsevier B.V., 2020-05-20)
The aim of this work was to study fast pyrolysis of three microalgae species in a continuous bench-scale conical spouted bed reactor at 500 °C. Bio-gas, bio-oil and bio-char yields have been determined and characterized ...
Experimental study and modeling of biomass char gasification kinetics in a novel thermogravimetric flow reactor
(Elsevier B.V., 2020-04-25)
[EN]This work pursues the validation of a new reactor for the evaluation of char gasification kinetics. This novel reactor allows continuous gas flow through the fixed bed sample and accurately monitoring the mass loss ...
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 ...
Bed symmetry in the fountain confined conical spouted beds with open-sided draft tubes
(Elsevier, 2022-05-13)
Bed symmetry has been analysed in fountain confined conical spouted beds operating with fine particles. Thus, vertical particle velocities and the spout shape have been determined in a wide range of spouting air velocities ...
