A study of the oxidehydration of 1,2-propanediol to propanoic acid with bifunctional catalysts

Bandinelli, Claudia; Lambiase, Barbara; Tabanelli, Tommaso; De Maron, Jacopo; Dimitratos, Nikolaos; Basile, Francesco; Concepción Heydorn, Patricia; López Nieto, José Manuel; Cavani, Fabrizio (Elsevier, 2019-07-25)

[EN] The gas-phase oxidehydration (ODH) of 1,2-propanediol to propionic acid has been studied as an intermediate step in the multi-step transformation of bio-sourced glycerol into methylmethacrylate. The reaction involves ...
Glycerol oxidehydration into acrolein and acrylic acid over W-V-Nb-O bronzes with hexagonal structure

Chieregato, Alessandro; Basile, Francesco; Concepción Heydorn, Patricia; Guidetti, Stefania; Liosi, Giuseppe; Soriano Rodríguez, Mª Dolores; Trevisanut, Cristian; Cavani, Fabrizio; López Nieto, José Manuel (Elsevier, 2012-12-12)

[EN] This paper deals with an investigation of hexagonal W-Nb-O and W-V-Nb-O bronzes as catalysts for the one-pot oxidehydration of glycerol into acrylic acid. In a previous work, we reported that the best yield to acrylic ...
Glycerol oxidehydration to acrylic acid on complex mixed-metal oxides

Chieregato, Alessandro (Universitat Politècnica de València, 2016-04-14)

[EN] The project of this Ph.D. thesis is based on a co-supervised collaboration between Università di Bologna, ALMA MATER STUDIORUM (Italy) and Instituto de Tecnología Química, Universitat Politècnica de València ITQ-UPV ...
Multielement crystalline and pseudocrystalline oxides as efficient catalysts for the direct transformation of glycerol into acrylic acid

Chieregato, Alessandro; Soriano Rodríguez, Mª Dolores; García-González, Ester; Puglia, Giuseppe; Basile, Francesco; Concepción Heydorn, Patricia; Bandinelli, Claudia; López Nieto, José Manuel; Cavani, Fabrizio (Wiley-VCH Verlag, 2015-01)

[EN] Glycerol surplus from biodiesel synthesis still represents a major problem in the biofuel production chain. Meanwhile, those in the acrylic acid market are looking for new processes that are able to offer viable ...
One-pot glycerol oxydehydration on multifunctional catalysts: influence of acid and redox properties on the catalytic performance

Chieregato, Alessandro; Soriano Rodríguez, Mª Dolores; Basile, Francesco; Liosi, Giuseppe; Zamora Blanco, Segundo; Concepción Heydorn, Patricia; Cavani, Fabrizio; López Nieto, José Manuel (Elsevier, 2014)

[EN] We report on a study of the key reaction parameters in glycerol oxidehydration into acrylic acid over W-V-Nb mixed oxides with a hexagonal tungsten bronze structure. This investigation demonstrated that the optimal ...
Structure-reactivity correlations in Vanadium containing catalysts for the one-pot glycerol oxidehydration to acrylic acid

Chieregato, Alessandro; Bandinelli, Claudia; Concepción Heydorn, Patricia; Soriano Rodríguez, Mª Dolores; Puzzo, Francesco; Basile, Francesco; Cavani, Fabrizio; López Nieto, José Manuel (John Wiley & Sons, 2017)

[EN] The design of suitable catalysts for the one-pot conversion of glycerol into acrylic acid (AA) is a complex matter, as only fine-tuning of the redox and acid properties makes it possible to obtain significant yields ...
Tungsten-Vanadium mixed oxides for the oxidehydration of glycerol into acrylic acid

Soriano Rodríguez, Mª Dolores; Concepción Heydorn, Patricia; López Nieto, José Manuel; Cavani, Fabrizio; Guidetti, Stefania; Trevisanut, C. (Royal Society of Chemistry, 2011)

[EN] In this paper we report on the one-pot transformation of glycerol into acrylic acid, catalyzed by W/V mixed oxides, with hexagonal tungsten bronze (HTB) structure. The reaction requires two different catalyst ...
Valorization of Bio-Alcohols into Added Value Chemicals

Balestra, Giulia (Universitat Politècnica de València, 2022-07-28)

[ES] El presente trabajo de investigación está centrado en la valorización y la mejora del bioetanol, empleando catalizadores heterogéneos, en un reactor de flujo continuo a escala de laboratorio. En primer lugar, en los ...
