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 ...
Effect of water and methanol concentration in the feed on the deactivation of In2O3-ZrO2/SAPO-34 catalyst in the conversion of CO2/CO to olefins by hydrogenation
(Elsevier, 2023-08)
On account of the superior performance of In2O3-ZrO2/SAPO-34 tandem catalyst in the direct synthesis of olefins from CO, CO2 and CO/CO2 mixture by hydrogenation, it is interesting to establish the conditions to avoid its ...
Setting up In2O3-ZrO2/SAPO-34 Catalyst for Improving Olefin Production via Hydrogenation of CO2/CO Mixtures
(MDPI, 2023-07-14)
The adequate configuration and the effect of the reduction was studied for the In2O3-ZrO2/SAPO-34 catalyst with the aim of improving its performance (activity and selectivity in the pseudo-steady state) for the hydrogenation ...
Boosting the activity in the direct conversion of CO2/CO mixtures into gasoline using ZnO-ZrO2 catalyst in tandem with HZSM-5 zeolite
(Elsevier, 2023-06)
The direct production of C5+ hydrocarbons from CO2/CO mixtures with methanol as intermediate is an attractive alternative for the production of gasoline from CO2 and syngas derived from biomass. With this purpose, the ...
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 ...
Kinetic modeling of the hydrocracking of polystyrene blended with vacuum gasoil
(Elsevier, 2023-01)
The kinetic modeling of the hydrocracking of a mixture of polystyrene (PS) and vacuum gasoil (VGO) over a PtPd/HY catalyst has been carried out. The reactions have been performed in a batch reactor under the following ...
A six-lump kinetic model for HDPE/VGO blend hydrocracking
(Elsevier, 2023-02)
A six lump-based kinetic model has been developed for the hydrocracking of high-density polyethylene (HDPE) blended with vacuum gas oil (VGO) over a PtPd/HY zeolite catalyst. The blend (20 wt% HDPE and 80 wt% VGO) has been ...
