La construcción de la biorrefinería Cellunolix® en Kajaani de St1 está en curso

By -


St1 Biofuels, subsidiaria de la empresa nórdica de energía St1 Nordic Oy y pionera en la producción de bioetanol derivado de residuos, está construyendo una planta de etanol celulósico en Kajaani (Finlandia). El blog informaba en Julio que Novozymes había anunciado un acuerdo para proveer la tecnología de enzimas para esta nueva biorrefinería que tendrá una capacidad anual de 10 millones de litros y representará una inversión de cerca de 40 millones de euros.

La construcción de la instalación, que empezó en la segunda mitad de 2015, está transcurriendo según lo planificado (nota de prensa). Varios tanques grandes ya han sido construidos y la instalación del equipamiento se está llevando a cabo durante el invierno. Las primeras pruebas comenzarán durante el verano y el suministro de materia prima y el comisionado se iniciarán a finales de 2016. Las fases de ingeniería y construcción están generando unos 200 empleos y la operación de la planta requerirá de entre 10 y 15 nuevos puestos indefinidos. La selección de personal para estas tareas empezará en el mes de mayo.

La planta se construirá y operará basándose en unas tecnologías de pretratamiento y procesado conocidas como Cellunolix® que utiliza serrín de coníferas (por ejemplo, pino y euforbio) como materia prima. La instalación estará localizada junto a un aserradero y será la primera del mundo en utilizar serrín de coníferas como materia prima para producir etanol celulósico a escala comercial. St1 Biofuels afirma que ha desarrollado una tecnología que recorta los costes de producción y logísticos, limitando la exposición al riesgo.

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...

Versión en Español Type of post: Fact sheet. Series: Biobased chemicals – Organic acids. Publication date: 05/05/2021. Last update: 05/05/2021. Description - Organic acid with 3 carbon atoms. - It is a clear, colourless, corrosive liquid with a characteristic acrid or tart smell. - Other names: prop-2-enoic acid. Applications - Formation of homopolymers or copolymers which are used in the manufacture of various adhesives, coatings, diapers, detergents, paints, plastics and textiles. The main use of crude acrylic acid is the generation of acrylate esters, followed by the production of polyacrylic acid, used mostly in superabsorbent polymers. - Chemical intermediate in multiple industrial processes. Conventional petrochemical route - Cracking of fossil naphtha to produce propylene / Oxidation of propylene. Main biobased routes - [3-HPA via] Fermentation of sugars to produce 3-hydroxypropionic acid (3-HPA) / Dehydration of 3-HPA. - [Biobased naphtha via] Cracking of biobased naphth...
