Influence of acidic properties of different solid acid catalysts for glycerol acetylation
(Elsevier Science, 2017-07)
The glycerol esterification with acetic acid is studied in this work using propylsulfonic functionalizedmesoporous silica (Pr-SO3H-SBA-15), and compared with H-ZSM-5 and H-Beta zeolites. The reactionwas carried out in a ...
Highly stable platinum monolith catalyst for the hydrogenation of vegetable oil
(Elsevier Science SA, 2022-01-13)
In the present work, a novel structured platinum catalyst where the Pt is supported on an anodized aluminum monolith was studied for the hydrogenation of sunflower oil. The catalytic tests were carried out in a monolithic ...
Yield of aromatics from naphthenics upon catalytic cracking
(Sociedade Brasileira de Química, 2012-07)
Cis- and trans-decalin were reacted over cracking catalysts to study the formation of aromatics in a particular fraction of the liquid products obtained in the fluid catalytic cracking process (FCC). A batch, fluidized bed ...
Liquid phase selective hydrogenation of cinnamaldehyde over copper supported catalysts
(Elsevier Science, 2012-01-31)
The selective hydrogenation of cinnamaldehyde is carried out in a batch reactor, at 100 °C and 1 MPa of H 2 using isopropyl alcohol as the solvent, over a series of copper supported catalysts: Cu/Al 2O 3, Cu/SiO 2 Cu/MCM-48, ...
Fermentative biohydrogen production from a novel combination of vermicompost as inoculum and mild heat-pretreated fruit and vegetable waste
(Green Wave Publishing of Canada, 2019-09)
This study reports for the first time on biohydrogen production by dark fermentation using a novel combination of mild heat-pretreated fruit and vegetable waste (FVW) as raw material and vermicompost as an economical source ...
Linear Algebra Controller Design Based on the Integral of Desired Closed-Loop Behavior: Application to Regulation and Trajectory Tracking in a Typical Chemical Process
(American Chemical Society, 2020-11)
This work presents a novel control technique that combines linear algebra-based controller (LABC) methodology with sliding surface concepts. An LABC is developed from a first-order plus dead time model of the process, which ...
Alternatives to rethink tomorrow: Biodiesel production from residual and non-edible oils using biocatalyst technology
(Pergamon-Elsevier Science Ltd, 2019-12-25)
Esterification and/or transesterification of a residue from soybean oil obtaining process, Jatropha hieronymi oil (non-edible), waste frying oil (sunflower) and commercial sunflower oil were studied for biodiesel production. ...
An energy-saving re-use strategy for the treatment of lignocellulosic biomass applied to the production of levulinc acid
(Elsevier, 2020-06)
A strategy for the re-use of spent liquors during the batch dilute acid treatment of lignocellulosic biomass was evaluated as an alternative to reduce the consumption of water and energy. Using the same spent liquor in the ...
Improvement of linear algebra controllers using sliding surface concepts: Applications to chemical processes
(Institute of Electrical and Electronics Engineers, 2021-08)
This work presents a novel control technique that combines concepts of Sliding Surface with a Linear Algebra methodology for controller design. The result is a controller with an improved robustness, while the chattering ...
Plant Oil Valorization by Cross-Metathesis Reactions: Synthesis of Fine Chemicals From Methyl Oleate
(Planta Piloto de Ingeniería Química, 2020-02)
This work studies the production of high-value compounds by the cross-metathesis of methyl oleate (MO) with ethylene, cinnamonitrile and cinnamaldehyde using the 2nd generation Hoveyda-Grubbs complex (HG) as catalyst, ...
