Adsorption of Tetramethylammonium Hydroxide (TMAH) on Y-type Zeolite

Chang S., Lu C., National Chung Hsing University, TW

Y-type zeolite have high TMAH removal efficiency when pH>4 with solid-liquid ratio (S/L) of 2 g/L in 20 minutes. The correlation coefficients of Langmuir and Freundlich isotherm models are 0.973 and 0.997, respectively. The exponential [...]

Iron doped spent tea waste charcoal as potential adsorbent for treatment of electroplating industry waste water

Butt R., Nazir R., Khan M.N., Hamid A., PCSIR, PK

Waste water from electroplating industry is heavily loaded with the heavy metals and is a potential threat to environment and human health. In this study the potentiality of spent tea waste charcoal has been determined [...]

Deep UV Light Emitting Diode Technology for compact Point-of-Use Water Disinfection Systems

Gaska I., Gaska R., Bilenko O., Bilenko Y., Shturm I., Smetona S., Bilenko O., Bilenko Y., Shatalov M., Bettles T., Gaska I., Gaska R., Gleason Z., Sim M., Oriard T., Sensor Electronic Technology, US

We reported in previous CleanTech conferneces about successful DUV LED application in POU (Point Of Use) disinfection systems; in this presentation we report on the performance results of a compact water disinfection system (WDS) that [...]

Lignocellulosic sugars as co-substrates for single cell oil and γ-linolenic acid production by Thamnidium elegans

Zikou E., Chatzifragkou A., Koutinas A.A., Papanikolaou S., Agricultural University of Athens, GR

Thamnidium elegans CCF-1465 was tested for its ability to produce lipid containing γ-linolenic acid (GLA), during its cultivation on mixtures of glucose and xylose, abundant sugars of lignocellulosic biomass. Experiments were conducted in both shake-flask [...]

Developing confectionery industry biorefineries

Tsakona S., Kopsahelis N., Chatzifragkou A., Papanikolaou S., Koutinas A.A., Agricultural University of Athens, GR

Food wastes are generated worldwide at significant quantities and could be regarded as a valuable renewable resource for biorefinery development aiming at the production of fuels, chemicals and materials.This study presents novel bioprocessing and biorefinery [...]

From Biogas To Syngas Over Ni Incorporated Ca and Mg Based Hydrotalcite-Like Catalysts

Yasyerli S., Topaloglu G., Dogu G., Gazi University, TR

Catalytic transformation of methane-carbon dioxide mixture, produced through anaerobic digestion of organic waste, to syngas is a promising route for the production of chemicals and fuels from biogas. Dry reforming of methane is expected to [...]

Pretreatment and Fractionation of Wheat Straw for Production of Fuel Ethanol and Value-added Co-products in a Biorefinery

Zhang X., Nghiem N.P., USDA ARS Eastern Regional Research Center, US

Wheat straw was used to demonstrate a process for production of ethanol and value-added co-products. The pretreatment of wheat straw was carried out using the soaking in aqueous ammonia (SAA) process. The pretreated wheat straw [...]

Valorization of by-product streams from the pulp and paper industry for succinic acid production

Pateraki C., Alexandri M., Papapostolou H., Vlysidis A., Papanikolaou S., Koutinas A., Agricultural University of Athens, GR

Spent sulphite liquor (SSL) is a by-product stream generated by the pulp and paper industry employing the sulfite pulping process. SSL contains high quantities of lignosulphonates and various C5 and C6 monosaccharides. The monosaccharides contained [...]

Determining the environmental benefit of artificial spider silk products

Lauterbach A.Y., Scheibel T., University of Bayreuth, DE

Spider silk is a highly interesting material with outstanding properties. Because the usage of natural spider silk for technical applications is not possible, the production of recombinant spider silk was established. This production process has [...]

Recent Results from Gas Loaded Nanoparticle-Type Cluster Power Units

Miley G.H., Kim K-J, Patel T.C., Lenuco LLC, US

This research is done in support of the development of modular 5 kW co-generation power LENR cells by LENUCO LLC. These modular units are stacked to provide powers up to 50 kW. A prototype unit [...]
