Patent number: 11185796Abstract: The present disclosure provides a fast and high-capacity intelligent cellulose-based oil-absorbing material and a preparation method and use thereof. The material includes an intelligent response layer and an adsorption layer. The intelligent response layer is a pH-responsive nanofiber layer with an adjustable pH response performance and is obtained by grafting hyperbranched polycarboxylic acid-modified polyethyleneimine on to carboxylated cellulose nanofibers. The hyperbranched polycarboxylic acid is prepared by melting and polycondensing at a high temperature, using trimethylolpropane as a core, citric acid as a reactive monomer, and p-toluenesulfonic acid as a catalyst. The adsorption layer is prepared by coating ferroferric oxide with the carboxylated cellulose nanofibers to prepare magnetic carboxylated cellulose nanofibers, and then modifying the magnetic carboxylated cellulose nanofibers with hexadecylamine.Type: GrantFiled: October 22, 2020Date of Patent: November 30, 2021Assignee: GUANGXI UNIVERSITYInventors: Chengrong Qin, Hui He, Lei Wang, Hongxiang Zhu, Chao Zhao, Rimei Chen, Zongyan Quan, Zhiping Chen

Publication number: 20210032139Abstract: To promote anaerobic digestion and delay calcification, one or more signal molecules are used to regulate the microenvironment of anaerobic granular sludge. In the process of anaerobic granular sludge treatment of papermaking wastewater, AHLs (N-acyl Hyperserine Lactones) are added to papermaking wastewater before the papermaking wastewater enters the anaerobic reactor. This may occur when the proportion of microorganism in anaerobic granular sludge VSS/TSS is less than 0.6. Further, the addition of the one or more signal molecules changes the community structure of the bacteria and methanogens, promoting anaerobic digestion and delay calcification. Additionally, the microenvironment of granular sludge is regulated by adding one or more micro-signal molecules to improve the number of bacteria susceptible to calcification, improve the anaerobic digestion rate of sludge that has not been calcified, and delay the calcification rate.Type: ApplicationFiled: June 30, 2020Publication date: February 4, 2021Inventors: Shuangfei Wang, Zhiwei Wang, Meiling Li, Shuangquan Yao, Jian Zhang, Jinghong Zhou, Peng Lu, HongXiang Zhu, Shuangxi Nie

Publication number: 20190345033Abstract: A high-purity chlorine dioxide gas may use hydrogen peroxide as a reducing agent and may use horizontal generator, evaporation crystallizer, dryer and other devices to produce chlorine dioxide gas (product) and sodium sulfate (by-product). Compared to the conventional chlorine dioxide preparation system, the chlorine dioxide reaction and the sodium sulfate crystallization are performed in two processes. These processes are relatively separate and independent, and continuously produce chlorine dioxide gas with high purity and low moisture content while the by-product salt cake is evaporated, crystallized, filtered and dried, thereby producing sodium sulfate, without generating solid and liquid waste.Type: ApplicationFiled: November 6, 2018Publication date: November 14, 2019Inventors: Shuangfei WANG, Chengrong QIN, Shuangxi NIE, Xueping SONG, Chen LIANG, Xinliang LIU, Zhiwei WANG, HongXiang ZHU
