NEW RESEARCH ARTICLE: Applications of supercritical technologies to CO2 reduction: Catalyst development and process intensification

Our economy relies on fossil fuels that can be converted into energy and chemicals, but this model is endangered by depletion of resources and environmental problems. To solve this dilemma, we can find inspiration in photosynthetic organisms that consider CO2 as a carbon source and not as waste. CO2 utilization processes have experienced a considerable […]

Scaling-Up Of SFEE, Identification Of Process Parameters On Product Characteristics And Economic Impact

A scaled-up SFEE equipment (Fig 1) was designed and used for producing sufficient amount of aqueous suspensions for PGSS-drying treatment. Using PGSS-drying water content of aqueous suspensions was extracted, and hence long-term stability of product was increased, without irreversible change on its morphology. The scaled-up SFEE equipment consists of an electrically tempered extractor vessel with […]

Meet María Anderez – PhD student on CO2 reduction project

She comes from Leibniz Institute for Catalysis, LIKAT (Rostock, Germany), where she focused on the homogeneous catalytic dehydrogenation of hydrogen carriers. During her thesis, she will study the CO2 reduction using lignocellulosic derivatives as reductans. CO2 reduction in hydrothermal environment using biomass as reductant In the last decades, CO2 has attracted more attention for its […]

Cellulose processing with ionic liquids and supercritical CO2

Ionic liquids have been demonstrated to be highly effective solvents for biomass processing for the production of biofuels and chemical feedstocks from renewable resources, such as lignocellulosic biomass. This ability has attracted numerous studies of ionic liquids for the pretreatment and fractionation of lignocellulosic biomass. Nevertheless the high viscosity of ionic liquids which is greatly […]

[Thesis]: Study of the improvement of cellulose processing in ionic liquid by using carbon dioxide by Joana M.C. Lopes

Dr. Joana M. C. Lopes defended her thesis on Wednesday 5th October 2016 at the University of Valladolid. The capacity of the ionic liquids (ILs) of dissolving high concentrations of cellulose and/or lignin at relatively low temperatures makes them promising solvents for the processing of lignocellulosic biomass waste. Many applications have been proposed over the years: pre-treatment for fermentation […]
