GTI evalúa el potencial de producir gas natural renovable a partir de residuos de madera

By -


Tipo de entrada: NOTICIA BREVE.

GTI ha editado un estudio muy interesante que pretende ser una guía para la conversión de una planta existente de biomasa en una instalación para producir Gas Natural Renovable (RNG por sus siglas en inglés) usando residuos leñosos y parte de la infraestructura existente. El estudio, preparado para CARB, PG&E, SoCalGas, Northwest Natural y SMUD, se llevó a cabo para entender mejor el valor, los beneficios y el coste de utilizar residuos de madera para reducir las emisiones de gases de efecto invernadero (GEI). La instalación seleccionada como referencia de diseño fue una planta de biomasa en Stockton (California).
Nota de prensa: “GTI Quantifies Opportunity to Produce Low-Carbon Renewable Natural Gas (RNG) from Wood Wastes”, 14/2/2019.
Estudio: "Low-Carbon Renewable Natural Gas (RNG) from Wood Wastes".

Figura 1. Portada del estudio "Low-Carbon Renewable Natural Gas (RNG) from Wood Wastes"

Puntos destacados:
- Nuevas instalaciones de producción de RNG basadas en las tecnologías comerciales cubiertas por el análisis podrían eliminar el 99% de los contaminantes del aire convencionales al comparar con plantas de biomasa en operación existentes.
- El estudio confirma la capacidad para producir grandes cantidades de RNG con una muy baja intensidad de carbono para uso en los sectores del transporte, industrial, comercial y energético residencial. En la configuración base del estudio, una planta podría desplazar aproximadamente 170,000 toneladas de emisiones de CO2 de vehículos cada año, lo que representa aproximadamente la cantidad emitida al conducir 400 millones de millas (casi 650 millones de km).
- Según el análisis, California tiene el potencial de producir decenas de miles de millones de metros cúbicos de RNG al año a partir de residuos que ahora están siendo utilizados para producir bioelectricidad. La tecnología de gasificación supone una opción adicional para ocuparse de los residuos de biomasa leñosa en California a la vez que se proporciona una fuente limpia de energía renovable.

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...
