Patent number: 12338132Abstract: A method for preparing an amorphous hierarchically porous UiO-66 is provided. Ammonium fluoride is added to promote dissolution of terephthalic acid (TPA) in water, and then zirconium nitrate is dissolved in water. Polyethylene glycol (PEG) shows high hydrophilicity, and ethoxy repeating unit in the PEG interacts with zirconium ions, thus promoting coordination self-assembly of metal ions and organic ligands. The zirconium ions react with carboxyl groups of the TPA through coordination. The coordination is achieved through chemical bonding between the zirconium ions and carboxyl oxygen atoms, thereby forming preliminary coordination polymer structures. As the coordination proceeds, these preliminary coordination polymer structures begin to self-assemble into short-range ordered network structures, in which water molecules act as a medium to help the zirconium ions and organic ligands ligate in space, thereby generating the amorphous hierarchically porous UiO-66.Type: GrantFiled: September 20, 2024Date of Patent: June 24, 2025Assignee: SHENZHEN POLYTECHNIC UNIVERSITYInventors: Xiaolin Li, Shilin Li, Wei Chen, Liang Zhang, Tao Gong

Publication number: 20250136491Abstract: It discloses an apparatus and a method for treating oil-containing sludge, wherein, a pressurized chamber is the main structure, and a mixture of carbonic acid in water, iron-rich biochar and polyaspartic acid is sprayed in pulses by a nano-aeration device inside the pressurized chamber. The carbonic acid is decomposed into supercritical CO2 by the nano-aeration device, reducing the viscosity of petroleum hydrocarbons in the oil-containing sludge synergistically with the polyaspartic acid. The iron-rich biochar promotes dissolution of petroleum hydrocarbons from the oil-containing sludge, thus enhancing the drive-off ratio of oil phase, and improving the decomposition of residual oil organics. In the treatment of oil-containing sludge according to the present invention, high temperature retting of the separated sludge with bacterial bran increases the degree of humification of the sludge, the treated sludge contains petroleum hydrocarbon below 1%, and can be directly available to plants.Type: ApplicationFiled: August 12, 2022Publication date: May 1, 2025Applicant: SHENZHEN POLYTECHNICInventors: Lei WANG, Beidou XI, Shaofeng LI, Yangyang WANG, Xiaoshu WANG, Yan SHAO, Jiancong LIU, Jin LIU, Jinsheng WANG
