Biofuels from algae

In my opinion, the production of biofuels and biobased chemicals from algae is one of the most fascinating topics in the sector of the biorefineries and it will be one of the niches of opportunity with highest potential in the medium and the long terms. This post pretend to be a very basic approach to the topic Algae-to-Biofuels through three general key points. Algae 1,2,3,4,5 Algae include a wide variety of photosynthetic organisms capable of transforming light, water and specific nutrients into products that can be used with commercial and industrial purposes. We can say that algae are sunlight-driven factories with potential to convert CO 2 into biofuels, high-value biochemical, food and feed. There are four algae cultivation technologies currently in use for commercial algae cultivation and proposed for algal biofuel production: extensive or open ponds, intensive or raceway ponds, closed photobioreactors in many designs and closed fermenter systems.

English version Sección: BIOCOMBUSTIBLES AVANZADOS Serie: HVO - Hidrotratamiento (HVO) – Conceptos, materias primas y especificaciones - Hidrotratamiento(HVO) – Ventajas sobre el biodiesel convencional y propiedades - Biorrefinerías de Aceites Vegetales Hidrotatados (HVO) – El auge del diésel renovable - Entradas: HVO                El acrónimo HVO significa en inglés “ Hydrotreated Vegetable Oils ” (“Aceites Vegetales Hidrotratados”) o ” Hydrogenated Vegetable Oils ” (“Aceites Vegetales Hidrogenados”). Clave del proceso: Tratamiento con hidrógeno. En el proceso de producción de HVO, el hidrógeno se usa para eliminar el oxígeno de los triglicéridos produciendo una mezcla de parafinas lineales, CO 2 y agua. Posteriormente, el producto de la primera etapa se isomeriza, siempre en presencia de hidrógeno, para ramificar las cadenas lineales con el propósito de mejorar las propiedades de flujo en frío de los productos finales. Por tanto, los HVO son

Conceptos generales El etanol (también conocido como alcohol etílico, alcohol para beber o simplemente alcohol) es un líquido volátil, inflamable e incoloro con la fórmula molecular C 2 H 6 O (también se puede escribir como CH 3 CH 2 OH y C 2 H 5 OH) y a menudo se abrevia como EtOH. La Asociación Europea de Etanol Renovable (ePURE) afirma que el mercado del etanol se puede dividir en tres segmentos: (1) Combustible : etanol utilizado como aditivo en la gasolina o como combustible alternativo. (2) Potable : etanol utilizado para producir bebidas espirituosas, como aditivo alimentario, para la extracción de aromas, para la conservación de alimentos y

Versión en Español Type of post: Fact sheet. Series: Biobased chemicals – Organic acids. Publication date: 25/05/2021. Last update: 25/05/2021. Description - C6 aliphatic dicarboxylic acid. - White crystalline powder. - Other names: hexanedioic acid; 1,4-butanedicarbocylic acid. Applications - Monomer for the production of nylon 6,6. - Monomer for the production of polyurethane. - Manufacture of plasticizers and lubricants. - Gelling and acidulant agent (food grade). Conventional petrochemical route - Oxidation of cyclohexane to produce KA oil (cyclohexanone and cyclohexanol) / Nitric acid oxidation of KA oil. During the final reaction, the highly potent GHG nitrous oxide (N2O, 300 times more potent than carbon dioxide) is formed. It has been estimated that replacing the current petrochemical-based process with one employing renewable precursors will reduce greenhouse gas emissions by up to 95%, depending on the process used (1).

Biorrefinerías de FDCA (ácido 2,5-furanodicarboxílico)

Fecha de publicación: 15/06/2017 Última actualización: 24/01/2018 Introducción 1,2,3,4,5 El ácido 2,5-furanodicarboxílico (FDCA, por sus siglas en inglés), también conocido como ácido ácido piromúcico, es un compuesto orgánico que fue detectado por primera vez en la orina humana. De hecho, una persona sana genera 3-5 mg/día. Se trata de un compuesto muy estable. Algunas de sus propiedades físicas, tales como insolubilidad en la mayor parte de disolventes y un punto de fusión muy alto (funde a 342ºC), parecen indicar la existencia de enlaces de hidrógeno intermoleculares. El FDCA posee dos grupos carboxilo, lo que le convierte en un monómero adecuado para reacciones de policondensación con dioles o diaminas. Es uno de los 12 principales compuestos químicos de alta valor añadido listados por el el DoE de los Estados Unidos en 2004. Esta lista se actualizó en 2010 y el FDCA fue incluido de nuevo, pero esta vez en un grupo junto con el furfural y el 5-hidroximetilfurfu
