Anellotech’s MinFree pretreatment technology reduces mineral content of loblolly pine biomass

By -


Type of post: NEWS IN BRIEF.

Anellotech has just announced that its MinFree™ technology has been demonstrated at a 20 tons/day scale. This proprietary biomass pretreatment process can significantly reduce mineral (ash) content of wood and other biomasses.
Press release: “Anellotech’s New Biomass Pre-Treatment Technology to Remove Minerals Successfully Demonstrated at 20 Metric Tons/Day Scale”, 4/7/2019.

Figure 1. Anellotech’s MinFree pretreatment technology reduces mineral content of loblolly pine biomass

Sustained trials using MinFree-treated loblolly pine at Anellotech’s TCat-8® pilot plant confirm the effectiveness of the process in dramatically extending catalyst life, making Anellotech’s Bio-TCat conversion technology increasingly efficient and competitive compared to fossil-sourced aromatics production.

MinFree™ is expected to provide similar results with other woody biomass (like eucalyptus and hard woods) and agricultural residues (like cotton straw, sugarcane bagasse and corn stover). Anellotech is in discussions with feedstock suppliers and other participants in the supply chain to select the next feedstock for development and commercialization with the MinFree™ process. 

MinFree™ also has application in the bioenergy sector. The technology removes high levels of mineral elements from agricultural residues which could cause fouling, erosion and corrosion. For example, a mineral-reduced feedstock can improve the efficiency, on-stream time and equipment life for pellet wood-fed biomass to energy plants.

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...

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...
