Exhaust air without organic chemicals

ID: F1509-09

Volatile organic compounds (VOCs) such as benzene and styrene can be hazardous to our wellness since well as the environment. Researchers are working on removing VOCs from commercial atmosphere emissions with the use of biotechnology. Three institutions have joined forces to eliminate VOCs from polluted industrial air emissions under the umbrella of the THEN AIR BIOTREAT project. Analysis collaboration led to the successful development of a novel hybrid biotechnology for treatment of hydrophilic VOCs. This set-up has been upgraded to industrial scale with a model product presently under operation. Definitely promising preliminary results have resulted in a patent. A pilot biotrickling filtration device had been set-up demonstrating efficient elimination of styrene from air emissions. From a financial and environmental point of view, this set-up proved superior to other technologies such as regenerative thermal oxidiser and activated carbon. Empirical information on filter overall performance has been generated to develop a mathematical model and control software to further optimise this technology. Researchers are currently testing a serial system incorporating a photocatalytic and biotrickling filter. In parallel, project members are developing a networking information platform for information processing and tracking of biotechnology systems. The project has advanced understanding of bioprocesses for VOC elimination from polluted air. Commercial exploitation of developed technologies will enhance the competition and visibility of participating institutions and promote the jobs of the scientists included. This has significant implications with respect to improving health and protecting the environment.

    Chemicals production without crude oil

    ID: F1508-08

    Hydrocarbons from crude oil are accustomed to create higher-value chemical compounds, but price that is increasing has affected the competition of manufacturers. Novel membrane layer reactors uses alternate feedstock to reduce reliance on oil. Short-chain alkanes with up to four carbons and carbon dioxide (CO2) present in normal gas, coal and biomass could replace the long-chain hydrocarbons from oil as feedstock for any other chemical compounds. However, they truly are very stable and unreactive particles, difficult to convert into additional value items. Alleviating the chemical industry's dependence on crude oil is a neccessity. Partners are developing membranes and catalysts to convert alternative feedstock into chemical compounds for power applications and services and products such as for example solvents, adhesives and coatings that are protective. Now, by the end associated with the second task period, experts are making important progress on all fronts. Novel ways of membrane planning have resulted in new membranes with improved selectivity at greater temperatures and gas that is tuneable properties. An important industrial chemical, has an operating temperature overlapping that of the new membranes in addition, a novel catalyst to speed the conversion of methanol and CO2 to dimethyl carbonate. Experts will also be applying revolutionary characterisation and evaluating protocols to boost the faculties of current membranes. A novel method predicts perovskite membrane traits from analysis of this powder beginning product, accelerating the growth procedure. In situ non-destructive assessment and analytical practices support optimisation of materials and processing under realistic conditions. Finally, long-lasting testing of hydrogen-selective palladium-based membranes has elucidated the key process of selectivity loss, pointing the way to extension of life time. The ultimate objective is demonstration of an membrane that is improved. Researchers have actually tested a 24-membrane steam-reforming reactor that achieved the needed conversion with much lower working temperatures than a process that is conventional. Catalytic membrane layer reactor technology developed will provide relief that is important the chemical industry, which as yet has been reliant on crude oil for feedstock to synthesise numerous services and products.
