In this work, the use of glucose as feedstock to produce the biofuel 5-ethoxymethylfurfural (EMF) is explored using a two-step system. The first step is optimized for the dehydration of glucose into 5-hydroxymethylfurfural ...

In the present work, a series of catalysts based on aluminum and zirconium oxides was studied for the transformation of glucose into 5-hydroxymethylfurfural. These catalysts were characterized by using experimental techniques, ...

CDs are newly discovered carbon nanoparticles that present unique properties. Each nanoparticle consists of a graphitic lattice core covered by a functionalized surface composed by several polar functional groups attached1,2. ...

Several sulfonated polymers, which are typical Brønsted acid catalysts, have been employed in the production of two biofuels: 5-ethoxymethylfurfural (EMF) and ethyl levulinate (EL) as main byproduct, and the catalytic ...

A Beta zeolite with a high Al:Si molar ratio was dealuminated and the resulting silanol nests were functionalized with Zr to generate Lewis acid sites, for the catalytic transfer hydrogenation of the carbonyl group of ...

En este trabajo se ha comprobado la efectividad de la zeolita beta (relación molar Si/Al= 10) en la isomerización de glucosa a fructosa y su deshidratación a HMF, y posterior eterificación a EMF, en un solo paso en etanol, ...

Biorefineries are industrial facilities where biomass is converted into chemicals, fuels and energy. The use of lignocellulose as raw material implies the development of pretreatments to reduce its recalcitrant character ...

Hexose sugars can be valorised under acidic conditions to produce the platform chemical 5-hydroxymethylfurfural (HMF), which can be transformed in a broad spectrum of chemicals with applications as biofuels or monomers for ...
