Tipo de entrada: NOTICIA BREVE.

Cordenka (el mayor productor de rayón industrial del mundo) y Stora Enso han firmado un acuerdo para desarrollar conjuntamente precursores de fibra de carbono biobasada. Este desarrollo está impulsado por la necesidad de fibra de carbono de alto rendimiento en el transporte, la construcción y la generación de energía.
Nota de prensa: “Stora Enso and Cordenka partner to develop bio-based carbon fiber materials”, 6/5/2020.
Entrada relacionada: “Stora Enso construirá una planta piloto para producir materiales carbonosos biobasados para almacenamiento de energía”, 22/7/2019.

Stora Enso ha estado desarrollando la tecnología para fabricar fibra de carbono a partir de materias primas basadas en madera (pulpa de celulosa y lignina) a escala de laboratorio. El acuerdo tiene como objetivo escalar el proceso de desarrollo de precursores hasta la escala piloto. El desarrollo de precursores se lleva a cabo con equipos especializados de hilado en el complejo de producción de Cordenka en Obernburg (Alemania). La empresa cuenta con el apoyo de BMC, propietario de Cordenka, como parte de su estrategia para ampliar el alcance de Cordenka a nuevos mercados en crecimiento y Asia.

La demanda de fibra de carbono está aumentando constantemente a una tasa de crecimiento anual del 10%. El objetivo del consorcio será desarrollar inicialmente fibra de carbono para aplicaciones industriales que requieran poco peso y alto rendimiento mecánico, como laminados utilizados en la fabricación de palas de rotor de energía eólica. Hoy, el 20% del suministro mundial de fibra de carbono es utilizado por la industria de la energía eólica.

Actualmente, la fibra de carbono se fabrica a partir de PAN (poliacrilonitrilo), que es una materia prima basada en el petróleo. Las materias primas para la fibra de carbono biobasada son la celulosa y la lignina. En el proceso de fabricación, la celulosa se convierte en viscosa y se mezcla con lignina. La mezcla se hila en fibra precursora que se convierte térmicamente en fibra de carbono.

Recent news about one of the DOE’s 12 Top Biobased Molecules. Rennovia Inc. and Johnson Matthey Process Technologies announced on July 16 that they have successfully started-up a mini-plant for production of glucaric acid from glucose using jointly developed technology. In March 2014, these companies embarked on a collaboration to develop, demonstrate and commercialize catalytic process technologies for the production of bio-based glucaric acid and adipic acid. Under the collaboration, Rennovia and JM Process Technologies work together in processes based on Rennovia’s technology for the catalytic aerobic oxidation of glucose to glucaric acid and the catalytic hydrogenation of glucaric acid to adipic acid. The final goal of the collaboration is to license a package enabling commercial production of these chemical products. The successful operation of this mini-plant is a major milestone in the journey to achieve this goal. The facility is located at the Johnson Matthey Process ...

Publication date: 25/04/2016 Last update: 25/04/2016 ABOUT THE SERIES OF POSTS “BIOREFINERY MODELS” This post belongs to a series called “ Biorefinery Models ”. This series is devoted to briefly describe the models or concepts of advanced biorefineries which have emerged in the last few years and that are rising currently. These models are simplified representations which enable us to understand in a simple way the structure and characteristics of a general biorefinery type. Some of these models refer to the type of feedstock while other focus on the technologies involved. A biorefinery may resemble these models or be the result of variations and combinations of them. It should be noted that although these paradigms are very useful and instructive, they show limitations in describing and classifying complex systems with high level of integration. In order to define and describe a specific complex case, the blog recommends use the classification proposed by IEA Bioenerg...

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 propieda...

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. Algal biof...
