CLAMBER is a R&D advanced biorefinery at demo scale located in Puertollano (Castilla-La Mancha, Spain). Currently, it has equipment capable of valorizing different biomass, both residual and cultivated, through biological transformations but these starting feedstocks may contain compounds with high added value which, with its existing facilities, is not able to take advantage of. There is a plethora of compounds that can be obtained by extraction.  In this sense, funding has been obtained from the European Regional Development Fund, in a percentage of 80% on the total costs of this supply, through an aid for the acquisition of scientific and technical equipment, corresponding to the State Program for the Generation of Knowledge and Scientific and Technological Strengthening of the R&D&i System, State Subprogram of Research Infrastructures and Scientific-Technical Equipment, Multi-Regional Operational Program of Spain, investment priority 1.A., within the framework of the “Plan Estatal de Investigación Científica y Técnica y de Innovación 2017-2020. Una manera de hacer Europa”.

Description of the supply

The equipment consists of a unit for extracting compounds of high added value from residual biomass or cultivated with supercritical fluids dedicated entirely to research. The solid is loaded in the extractor basket. The CO2 enters the extractor in supercritical conditions and extracts the desired product, leaving the top of it. In the first separator, the first fractionation takes place, when working under less pressure, the CO2 loses solvent power. The CO2 is directed to a second separator that works at a lower pressure than the first one, where a second fractionation occurs. The CO2 is filtered and recirculated to its storage tank for reuse later.

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...

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...
