Conversion of levulinic acid derived valeric acid into a liquid transportation fuel of the kerosene type

Corma Canós, Avelino; Oliver-Tomás, Borja; Renz ., Michael; Simakova, Irina (Elsevier, 2014)

[EN] In the transformation of lignocellulosic biomass into fuels and chemicals carbon-carbon bond formations and rising hydrophobicity are highly desired. The ketonic decarboxylation fits these requirements perfectly as ...
Conversión de biomasa a productos químicos de interés y keroseno mediante descarboxilación cetónica e hidrodesoxigenación

Oliver Tomás, Borja (Universitat Politècnica de València, 2013-06-24)

[ES] Transformación de ácidos carboxílicos procedentes de la biomasa en productos químicos y keroseno. Se estudió la descarboxilación cetónica del ácido decanoico sobre diversos óxidos metálicos y de diferentes ácidos ...
Direct conversion of carboxylic acids (C-n) to alkenes (C2n-1) over titanium oxide in absence of noble metals

Oliver-Tomás, Borja; Renz, Michael; Corma Canós, Avelino (Elsevier, 2016-05-01)

Carbon-carbon bond formations and deoxygenation reactions are important for biomass up-grading. The classical ketonic decarboxylation of carboxylic acids provides symmetrical ketones with 2n+1 carbon atoms and eliminates ...
Effect of the C-alpha substitution on the ketonic decarboxylation of carboxylic acids over m-ZrO2: the role of entropy

Oliver-Tomás, Borja; Gonell-Gómez, Francisco; Pulido, Angeles; Renz, Michael; Boronat Zaragoza, Mercedes (Royal Society of Chemistry, 2016)

[EN] The kinetics of the ketonic decarboxylation of linear and branched carboxylic acids over m-ZrO2 as a catalyst has been investigated. The same apparent activation energy is experimentally determined for the ketonic ...
Evaluation of hydrothermal carbonization in urban mining for the recovery of phosphorus from the organic fraction of municipal solid waste

Oliver-Tomás, Borja; Hitzl, Martin; Owsianiak, Mikolaj; Renz, Michael (Elsevier, 2019-08)

[EN] The organic fraction of municipal solid waste was identified as an alternative phosphorus resource: hydrothermal carbonization provided phosphorus-rich hydrochar. Two alternative valorization pathways can be considered ...
High Quality Biowaxes from Fatty Acids and Fatty Esters: Catalyst and Reaction Mechanism for Accompanying Reactions

Oliver-Tomás, Borja; Renz, Michael; Corma Canós, Avelino (American Chemical Society, 2017-11-15)

[EN] Biowaxes are interesting materials for pharmaceutical industry and consumer goods. Here the production of waxes from alternative renewable resources has been evaluated on the basis of the ketonic decarboxylation of ...
Ketone Formation from Carboxylic Acids by Ketonic Decarboxylation: The Exceptional Case of the Tertiary Carboxylic Acids

Oliver-Tomás, Borja; Renz, Michael; Corma Canós, Avelino (John Wiley & Sons, 2017-09-18)

[EN] For the reaction mechanism of the ketonic decarboxylation of two carboxylic acids, a -keto acid is favored as key intermediate in many experimental and theoretical studies. Hydrogen atoms in the -position are an ...
Ketonic decarboxylation reaction mechanism: A combined experimental and DFT study

Pulido Junquera, Maria Angeles; Oliver Tomás, Borja; Renz, Michael; Boronat Zaragoza, Mercedes; Corma Canós, Avelino (Wiley-VCH Verlag, 2013)

The ketonic decarboxylation of carboxylic acids has been carried out experimentally and studied theoretically by DFT calculations. In the experiments, monoclinic zirconia was identified as a good catalyst, giving high ...
Transformación de biomasa a productos químicos de interés y carburantes mediante descarboxilación cetónica e hidrodesoxigenación

Oliver Tomás, Borja (Universitat Politècnica de València, 2017-11-03)

The purpose of the present thesis was the use and valorisation of biomass platform molecules or their derivatives, applying the principles of sustainable chemistry. The reaction of ketonic decarboxylation of carboxylic ...
Transformation of Organic Household Leftovers into a Peat Substitute

Hernández-Soto, Maria Consuelo; Hernández-Latorre, Marisa; Oliver-Tomás, Borja; Ponce, Estefanía; Renz, Michael (Journal of Visualized Experiments, 2019-07)

[EN] A two-step procedure is described for the synthesis of a carbon material with a similar composition and properties as peat. The produced hydrochar is made suitable for agricultural applications by removing plant growing ...
