Kinetic modelling of the one-step conversion of aqueous ethanol into 1,3-butadiene over a mixed hemimorphite-HfO2/SiO2 catalyst
(Elsevier, 2021-06)
A kinetic model for the one-step conversion of ethanol into 1,3-butadiene over a mixed hemimorphite-HfO2/SiO2 catalyst has been developed, which, as a novelty, accounts for the effect of water content in ethanol on the ...

Ethanol conversion into 1,3-butadiene over a mixed Hf-Zn catalyst: Effect of reaction conditions and water content in ethanol
(Elsevier, 2019-10)
Assessment of catalyst performance is necessary for process design in order to evaluate the effect of reaction conditions on process economics and configuration. In this work, the combined effect of reaction conditions and ...

On the comprehension of the gas split in loop seal devices
(Elsevier, 2022)
Gas distribution through the chambers of a loop seal in circulating fluidized bed (CFB) units is still difficult to predict and often misunderstood. Dedicated experiments were carried out in an isolated loop seal to assess ...

PH-Controlled fermentation of strawberry waste as phenol solubilisation method
(Elsevier, 2020)
The present study aims to use pH as a control parameter for the accumulation of target compounds. Solubilisation of wasted strawberry through fermentation at different operational pH (pH 4, 7, and 9) was evaluated. Methane ...

Design and performance analysis of a solar dual fluidized bed gasifier
(Elsevier, 2023-04)
The potential to conduct allothermal steam-gasification of biomass using a dual fluidized bed gasifier (DFBG) assisted by solar energy has already been conceptually proposed. In this paper the design and operation of a ...

Ethanol conversion into 1,3-butadiene over a mixed Hf-Zn catalyst: A study of the reaction pathway and catalyst deactivation
(Elsevier, 2019)
Some fundamental and practical aspects of a Hf-Zn catalyst, with a nominal composition of 3.0 wt% Hf and 9.3 wt% Zn, and prepared as a physical mixture of Hf/SiO (85 wt%) and the zinc-silicate hemimorphite (15 wt%), have ...
