Regenerability of a Ni catalyst in the in-line catalytic steam reforming of biomass pyrolysis volatiles
(Elsevier, 2018-12)
A study has been carried out of the regenerability of a commercial Ni catalyst used in the steam reforming of volatiles from biomass pyrolysis, determining the evolution of the reaction indices in successive reaction-regeneration ...
Role of operating conditions in the catalyst deactivation in the in-line steam reforming of volatiles from biomass fast pyrolysis
(Elsevier, 2017-12-09)
The effect of reforming conditions (temperature, space time and steam/biomass ratio (S/B)) has been studied in the continuous biomass pyrolysis and in-line catalytic steam reforming process in order to establish suitable ...
Taking advantage of the excess of thermal naphthas to enhance the quality of FCC unit products
(Elsevier B.V., 2020-09-26)
Today, many European refineries finish up with excess of low-quality thermal naphthas that are hard to be marketed and, commonly, end being absorbed by catalytic naphthas at the expense of their higher quality. In this ...
Kinetic modeling of the direct synthesis of dimethyl ether over a CuO-ZnO-MnO/SAPO-18 catalyst and assessment of the CO2 conversion
(Elsevier, 2018-12-01)
A kinetic model has been established for the direct synthesis of dimethyl ether (DME) from syngas and CO2 feeds. The kinetic parameters have been determined fitting the experimental results obtained using a CuO-ZnO-MnO/SAPO-18 ...
Lessening coke formation and boosting gasoline yield by incorporating scrap tire pyrolysis oil in the cracking conditions of an FCC unit
(Elsevier, 2020-11-15)
We have studied the effect of adding scrap tire pyrolysis oil (STPO) as feed or co-feed in the cracking of vacuum gasoil (VGO) using a commercial equilibrated catalyst. The cracking experiments were performed in a laboratory ...
Energetic viability of a polyolefin pyrolysis plant
(American Chemical Society, 2018-03)
The energetic viability of a polyolefin pyrolysis unit that could be installed in a refinery plant was examined. Thermal pyrolysis at 500 and 700 degrees C, and the catalytic cracking by means of HZSM-5 and HY catalysts ...
Implementation of a borescopic technique in a conical spouted bed for tracking spherical and irregular particles
(Elsevier, 2019-05-22)
[ES] Se ha desarrollado y validado una metodología basada en la técnica boroscópica para seguir el movimiento del sólido dentro de un reactor spouted bed cónico. El procedimiento desarrollado y perfeccionado permite ...
Hydrogen production by steam reforming of bio-oil/bio-ethanol mixtures in a continuous thermal-catalytic process
(Elsevier, 2014-04-24)
The feasibility of the steam reforming of bio-oil aqueous fraction and bio-ethanol mixtures has been studied in a continuous process with two in-line steps: thermal step at 300 ºC (for the controlled deposition of pyrolytic ...
Influence of the support on Ni catalysts performance in the in-line steam reforming of biomass fast pyrolysis derived volatiles
(Elsevier, 2018-02-06)
The influence the support has on the performance of Ni catalysts used in the reforming of biomass fast pyrolysis volatiles has been assessed. Accordingly, five catalysts have been prepared by wet impregnation method, namely ...
Insight into the deactivation and regeneration of HZSM-5 zeolite catalysts in the conversion of dimethyl ether to olefins
(ACS, 2018-09-19)
The impact of different process variables affecting the coking and rejuvenation of HZSM-5 zeolite catalyst has been studied during the conversion of dimethyl ether (DME) to olefins in a fixed bed reactor. Those variables ...
