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 ...
Evaluating catalytic (gas-solid) spectroscopic cells as intrinsic kinetic reactors: Methanol-to-hydrocarbon reaction as a case study
(Elsevier, 2022-12)
Commercial spectroscopic gas-solid cell reactors are routinely used to analyze the dynamics of the catalyst (catalyst pelletized as a disc) structure and retained/adsorbed species using multiple operando techniques. These ...
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 ...
On the dynamics and reversibility of the deactivation of a Rh/CeO2-ZrO2 catalyst in raw bio-oil steam reforming
(Elsevier, 2019-01-28)
The deactivation mechanism of a commercial Rh/CeO2-ZrO2 catalyst in raw bio-oil steam reforming has been studied by relating the evolution with time on stream of the bio-oil conversion and products yields and the physicochemical ...
The intrinsic effect of co-feeding water on the formation of active/deactivating species in the methanol-to-hydrocarbons reaction on ZSM-5 zeolite
(Royal Society Chemistry, 2021-02-21)
Water is formed and added in the conversion of methanol-to-hydrocarbons, slowing down both the reaction and deactivation rates. This work aims to clarify the selective nature of water quenching on a ZSM-5 zeolite catalyst ...
Screening hydrotreating catalysts for the valorization of a light cycle oil/scrap tires oil blend based on a detailed product analysis
(Elsevier, 2019-11-05)
Predicting the hydrotreating performance of industrial catalysts used for upgrading heavy oils is hampered by the unknown chemistry behind it. In this work, we have used a set of chromatographic and mass spectrometric ...
Stability of an acid activated carbon based bifunctional catalyst for the raw bio-oil hydrodeoxygenation
(Elsevier, 2016-10-11)
The performance (activity, selectivity and stability) of a Pt-Pd catalyst supported on a phosphorus-containing activated carbon (ACP) has been studied in the hydrodeoxygenation (HDO) of raw bio-oil, and compared with another ...
Spectro-kinetics of the methanol to hydrocarbons reaction combining online product analysis with UV–vis and FTIR spectroscopies throughout the space time evolution
(Elsevier, 2022-04)
The well-studied methanol to hydrocarbons reaction over a ZSM-5 zeolite catalyst has been used to develop a spectro-kinetic approach to obtain an overall reaction mechanism involving both retained species and gas-phase ...
