Role of Zr loading into In2O3 catalysts for the direct conversion of CO2/CO mixtures into light olefins
(Elsevier, 2022-08-15)
The effect of the ZrO2 content on the performance (activity, selectivity, stability) of In2O3-ZrO2 catalyst has been studied on the hydrogenation of CO2/CO mixtures. This effect is a key feature for the viability of using ...
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 ...
Effect of reaction conditions on the deactivation by coke of a NiAl2O4 spinel derived catalyst in the steam reforming of bio-oil
(Elsevier, 2021-11-15)
[EN]The steam reforming of bio-oil is a promising and economically feasible technology for the sustainable H-2 production, yet with the main challenge of designing highly active and stable catalysts. This work aimed to ...
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 ...
Enhancing the performance of a PtPd/HY catalyst for HDPE/VGO hydrocracking through zeolite desilication
(Elsevier, 2022-12)
The valorization of post-consumer waste plastic in a refinery is an attractive initiative to avoid environmental problems caused by the poor plastic waste management. The modification of a bifunctional PtPd/HY catalyst ...
Study on the role of the reaction time in the upcycling of HDPE by co-hydrocracking it with VGO
(Elsevier, 2023-03)
Pursuing the aim of improving the current waste plastics management strategy, we have investigated the co-hydrocracking of high-density polyethylene (HDPE) with vacuum gasoil (VGO) over a PtPd/HY catalyst for converting ...
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 ...
