Autor: Jakob Munkholt Christensen, Lars Saaby Pedersen, Daniel Bo Larsen, Soheila Ghafarnejad Parto, Anker Degn Jensen, Emma Kathrine Jørgensen, Jens Ø. Duus

Publikováno v: Sustainable Energy & Fuels. 4:1844-1854

Beech wood was directly converted into lignin derived monomers and dimers and holocellulose derived light hydrocarbons in the presence of a sulfided NiMo/γ-Al2O3 catalyst in ethanol medium at 200 to 300 °C. The reaction products were carefully anal

Effect of Water Content of Synthetic Hydrogel on Dehydration Performance of Nanoporous LTA Zeolite Membranes

Autor: Saeed Shirazian, Seyed Nezameddin Ashrafizadeh, Soheila Ghafarnejad Parto

Publikováno v: International Journal of Applied Ceramic Technology. 11:793-803

Nanoporous LTA-type zeolite membranes were synthesized on α-Al2O3 disk as substrate using secondary growth method. A gel formula of 1 Al2O3: 2 SiO2: 3.4 Na2O: W H2O in molar basis was chosen while its water content (W) was varied. Four levels of wat
