Sappi escalará una tecnología para producir xylitol y furfural en Sudáfrica

By -


Tipo de entrada: NOTICIA BREVE.

El mes pasado, Sappi confirmaba que construirá una planta de demostración para avanzar en el escalado de la tecnología Xylex® que permite producir xilitol y furfural (véase nota de prensa, 18/7/2018).

Ubicación
La planta se ubicará junto a la instalación existente de extracción de azúcares y lignina en la fábrica de Sappi en Ngodwana (Sudáfrica).
La papelera produce 330.000 toneladas de pulpa de papel, 210.000 toneladas de pasta para disolver y 380.000 toneladas de papel (periódico y cartón kraft para envasado) al año.
Materia prima
Azúcares C5.
Productos
- Xilitol: La estrategia a futuro de Sappi pasa por penetrar en la cadena de valor del xilitol con una planta de producción a escala comercial.
- Furfural: Sappi pretende conseguir varios consorcios en la cadena de valor de los furanos.
Cronología
- 2016: Inversión en una planta de demostración en la fábrica de Ngodwana para extraer azúcares hemicelulósicos y lignina procedentes de la producción de pasta para disolver.
- 2017: Se comisiona la planta. Después de 12 meses de operación, la planta ha superado con creces los objetivos de coste, ciclo de tiempo y rendimiento.
- Más tarde en 2017: Sappi le compra a Plaxica la tecnología patentada Xylex para la hidrólisis y limpieza de azúcares C5.
- julio de 2018: Sappi confirma el escalado de la tecnología Xylex.
- Q1 2019: Se comisionará la nueva planta.
- Dependiendo de que los resultados sean exitosos y de futuras aprobaciones,  Sappi podría construir plantas comerciales para la producción de xilitol y furfural en sus fábricas de EEUU y Sudáfrica.

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.
