Tipo de entrada: NOTICIA BREVE.

Covestro y sus socios han desarrollado un proceso para obtener anilina a partir de biomasa. Tras este avance en el laboratorio, Covestro está trabajando ahora para escalar el proceso de producción.
Nota de prensa (Covestro): “Circular Economy - Aniline from plants”, 26/5/2020.

Figura 1. Covestro está trabajando en el escalado de un proceso de producción de anilina biobasada

La industria actualmente obtiene la anilina a partir del benceno, una materia prima basada en el petróleo. En mayo de 2017, Covestro anunció haber logrado un gran avance para el uso de materias primas de origen vegetal en la producción de anilina. El fabricante de materiales colaboró con socios (University of Stuttgart, el CAT Catalytic Center de la Universidad RWTH de Aquisgrán y Bayer AG) en la creación de un proceso completamente nuevo, que ahora se está desarrollando y mejorando.

El proceso utiliza un microorganismo como catalizador para convertir los azúcares industriales en un precursor de anilina. En un segundo paso, la anilina se produce mediante catálisis química. Esto significa que el 100% del carbono en la anilina proviene de materias primas renovables.

Covestro necesita anilina como precursor de la espuma rígida de poliuretano, un material aislante altamente eficiente utilizado en edificios y sistemas de refrigeración. Poder obtener la anilina a partir de biomasa es un paso clave para que las industrias química y del plástico sean menos dependientes de las materias primas fósiles y de las fluctuaciones del mercado. La nueva tecnología produce anilina con una huella de CO2 más favorable que la fabricada con tecnología convencional. Y las reacciones tienen lugar en condiciones más suaves.

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...
