Oxidative Fast Pyrolysis of High-Density Polyethylene on a Spent Fluid Catalytic Cracking Catalyst in a Fountain Confined Conical Spouted Bed Reactor
(American Chemical Society, 2022-11)
The oxidative fast pyrolysis of plastics was studied in a conical spouted bed reactor with a fountain confiner and draft tube. An inexpensive fluid catalytic cracking (FCC) spent catalyst was proposed for in situ catalytic ...
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 ...
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 ...
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 ...
Syngas production by bio-oil steam gasification in a fountain confined conical spouted bed reactor
(Elsevier, 2023-08)
The combination of delocalized units for the fast pyrolysis of biomass to produce bio-oil followed by centralized units for the gasification of bio-oil appears as an economically attractive option for the full-scale ...
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 ...
Solid-fluid mixing behavior of conical spouted beds with internal devices
(Elsevier, 2023-09)
The effect of draft tubes and fountain confiner on the gas and solids mixing behavior is studied in conical
spouted beds. Accordingly, the bed porosity has been determined in different hydrodynamic regimes of
1:1; 1:25 ...
Appraisal of agroforestry biomass wastes for hydrogen production by an integrated process of fast pyrolysis and in line steam reforming
(Elsevier, 2023-12)
The pyrolysis and in line steam reforming of different types of representative agroforestry biomass wastes (pine wood, citrus wastes and rice husk) was performed in a two-reactor system made up of a conical spouted bed and ...
