Patent number: 11912623Abstract: A fluidized solidified soil based on gold tailings includes the following raw materials in parts by mass: 75 parts to 80 parts of gold tailings, 5.2 parts to 13 parts of a dispersant solution, and 9 parts to 16 parts of a solidifying material. A preparation method includes the following steps: mixing the gold tailings with the dispersant solution, and then stirring to obtain a suspension slurry of the gold tailings; and adding the solidifying material, and stirring to obtain the fluidized solidified soil. In the present disclosure, the gold tailings are used as a main material, combined with a special dispersant solution and a special solidifying material, and a fluidized solidified soil is prepared with fluidity suitable for pumping and a certain strength after hardening. The fluidized solidified soil prevents the pollution caused by gold tailings landfilling, and can be used as a filling material for various construction projects.Type: GrantFiled: May 12, 2023Date of Patent: February 27, 2024Assignees: WUHAN INSTITUTE OF TECHNOLOGY, The College of Post and Telecommunication of WITInventors: Zunqun Xiao, Caiyun Xu, Fuqi Wang, Jian Lin, Hui Wang, Zhentao Lv, Yanbin Chang, Haitao Liu, Yinlei Shi, Keqi Luo, Minghui Deng, Puyu Li, Yuepeng Zheng

Patent number: 10637068Abstract: A gas diffusion electrode for an electro-synthetic or electro-energy cell, for example a fuel cell, including one or more gas permeable layers, a first conductive layer provided on a first side of the gas diffusion electrode, and a second layer, which may be a second conductive layer, provided on a second side of the gas diffusion electrode. The one or more gas permeable layers are positioned between the first conductive layer and the second layer, which may be a second conductive layer, and the one or more gas permeable layers provide a gas channel. The one or more gas permeable layers are gas permeable and substantially impermeable to the liquid electrolyte. The porous conductive material is gas permeable and liquid electrolyte permeable. The gas diffusion electrode can be one of a plurality of alternating anode/cathode sets.Type: GrantFiled: December 21, 2017Date of Patent: April 28, 2020Assignee: AquaHydrex, Inc.Inventors: Gerhard Frederick Swiegers, Stephen Thomas Beirne, Jun Chen, Caiyun Wang

Publication number: 20190256991Abstract: An electrode for a water splitting device, the electrode comprising a gas permeable material, a second material, for example a further gas permeable material, a spacer layer positioned between the gas permeable material and the second material, the spacer layer providing a gas collection layer and a conducting layer. The conducting layer can be provided adjacent to or at least partially within the gas permeable material. The gas collection layer is able to transport gas internally in the electrode. The gas permeable materials can be gas permeable membranes. Also disclosed are electrochemical cells using such an electrode as the cathode and/or anode, and methods for bringing about gas-to-liquid or liquid-to-gas transformations, for example for producing hydrogen.Type: ApplicationFiled: November 21, 2018Publication date: August 22, 2019Inventors: Gerhard Frederick SWIEGERS, Jun CHEN, Stephen Thomas BEIRNE, Caiyun WANG
