Official opening of the cellulosic ethanol biorefinery of Dupont in Iowa

By -


DuPont will open its 30-million-gallon cellulosic ethanol biorefinery in Nevada (Iowa, USA) on October 30. The Bioenergy Technologies Office (BETO) Director, senior government officials, DuPont staff and local farmers will attend the grand opening ceremony and plant tour. The biorefinery will be fueled by corn stover biomass harvested from a 30-mile radius around the facility. According to DuPont, the plant has provided many job and financial opportunities for this rural area: 1,000 construction-related jobs, 85 permanent jobs at the plant, 500 local farmers to supply the corn stover and 150 people involved in collection, transportation and storage of seasonal feedstock.

The completion of this biorefinery is a key milestone in the emerging production of cellulosic ethanol. In fact, it is the largest of the four commercial-scale plants (based on enzymatic conversion pathways) currently in operation in the United States: ACE Project (Iowa, 2 Mgal/y), Project Liberty (Iowa, 20 Mgal/y), Hugoton Biorefinery (Kansas, 25 Mgal/y) and Nevada Biorefinery (Iowa, 30 Mgal/y).

Over the last years, DuPont has invested hundreds of millions of dollars to deliver on the potential of cellulosic ethanol. A demonstration facility in Vonore (TN, USA) has generated the data necessary for commercial production. This 250,000-gallon demo plant began operation in 2009 working in partnership with Genera Energy and The University of Tennessee Biofuels Initiative. Also, DoE has supported DuPont by funding key bioenergy conversion technologies and collaborating on research and development projects. In total, DoE has contributed more than $51 million dollars to make this project come true.

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...
