A method for energy-positive combined desalination and advanced wastewater treatment Published: 11/12/2024 Inventor(s): Veera Gnaneswar Gude, Umesh Ghimire, Bahareh Kokabian A method for energy-positive combined desalination and advanced wastewater treatment A novel bio electrochemical migration anammox process to accomplish a resource-efficient nutrient energy water synergy. Background The scientific rationale for the proposed nitritation-anammox process stems from the anammox reaction stoichiometry. The physical... Catalytic Thermal Molecular Welding Method for Synthesizing Multi-Layer Nano-shell Structure-based Graphene Materials from Lignin Resources Published: 8/15/2023 Inventor(s): Jilei Zhang, Qiangu (Jeremy) Yan, Zhiyong Cai Technology overview A catalytic thermal molecular welding method for making graphene-based materials. Background There are several methods for making graphene-based materials, most notably the CVD process being the most promising method because it is inexpensive and produces large-area graphene. The CVD process is where the hydrocarbon-based gas... Synthesis Methods of Graphene from Lignin (SMGL) Published: 6/28/2024 Inventor(s): Jilei Zhang, Zhiyong Cai, SungKwang Mun Overview of Technology A synthesis method of graphene nanosheets from lignin using thermal treatment processes. This subject matter relates to a method for synthesizing carbon nanomaterials such as graphene nanosheets from wood by-products such as lignin using a thermal treatment process. Background Lignin refers to: kraft lignin (thiolignin)... Esterification, Acetalization and/or Ketalization to Upgrade Bio-oils to Boiler or Space Heating Fuels Published: 6/29/2022 Inventor(s): Philip Steele, Fei Yu, Sandun Fernando, Xuejun Ye Overview of Technology The technology is a development of a bio-oil sonification and esterification process that reduces bio-oil water content and acidity while significantly increasing higher heating value (HHV). The increase in HHV moves bio-oil to an energy level of 80% of No. 2 fuel oil, making the upgraded bio-oil much more competitive as a liquid... The Production of Biodiesel from Waste Sludges and Biosolids from Wastewater Treatment Plants Published: 8/15/2023 Inventor(s): W. Todd French, Mark Zappi, Rafael Hernandez, Darrell Sparks, Stephen Dufreche Overview of technology A biofuel that provides a more sustainable and environmentally friendly fuel source alternative to petroleum-based fuels Background Biodiesel can be produced from any plant or animal fat such as the oils derived from corn, rice, peanuts, coconut, poultry, beef and pork. Biodiesel can replace and or displace petroleum diesel...
