2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) is an extraordinarily toxic substance that is produced as an unwanted side product in the industrial synthesis of 2,4,5-trichlorophenol, an intermediate in the manufacture of the herbicide 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) (1, 2). Because of its chemical stability and its lipophilic nature, the possibility exists that TCDD released into the e...

The global demand for energy is increasing and the detrimental consequences of rising greenhouse gas emissions, global warming and environmental degradation present major challenges. Solar energy offers a clean and viable renewable energy source with the potential to alleviate the detrimental consequences normally associated with fossil fuel-based energy generation. However, there are two inher...

Duckweed biomass is gasified in a thermochemical-based superstructure to produce gasoline, diesel, and kerosene using a synthesis gas intermediate. The superstructure includes multiple pathways for conversion of the synthesis gas to liquid hydrocarbons via Fischer−Tropsch synthesis or intermediate methanol synthesis. Low-temperature and high-temperature Fischer−Tropsch processes are examined us...

KCoMoS2 was supported on various carbon support materials to study the effect synthesis gas conversion. Next two activated carbons with high micropore volume, a traditional alumina (?-Al2O3) and its coated form (CCA) were studied for comparison. Coating increases selectivity alcohols, but AC-supported catalysts show even higher alcohol selectivities yields, especially at temperatures where conv...
