Patent number: 10273412Abstract: The present invention is to provide a method for carbonization of crop straws and a device thereof. Pyrolysis process is controlled by regulating the feeding of oxygen during said pyrolysis process, and pyrolysis and carbonization are respectively conducted in separate pyrolysis and carbonization pools, wherein the straws are pyrolyzed in said pyrolysis pool and entered into said carbonization pool to be carbonized. The present invention can quickly raise the temperature of the pyrolysis process, shorten the time of the pyrolysis process, and improve the pyrolysis carbonization efficiency.Type: GrantFiled: April 22, 2016Date of Patent: April 30, 2019Assignee: SHANXI SUPPLY AND MARKETING COOPERATIVEInventors: Xiaoguang Wang, Jingyong Jing, Shuqin Zhang

Patent number: 10099931Abstract: A method for directly preparing an empty shell type small grain ZSM-5 molecular sieve. The method comprises: uniformly mixing and stirring an organic template agent, a silicon source and water; dripping an aqueous solution of an aluminum source into the mixture; preserving room temperature, and continuously stirring for a period of time; and performing hydrothermal crystallization, and washing, drying and roasting the obtained product to obtain the molecular sieve. The molecular sieve has high degree of crystallinity and uniform particle size. Moreover, the method requires short time, simple operation and only one step, no extra surfactant is needed, and secondary acid and alkali treatment is not needed.Type: GrantFiled: July 14, 2015Date of Patent: October 16, 2018Assignees: RESEARCH INSTITUTE OF SHAANXI YANCHANG PETROLEUM (GROUP) CO., LTD., DALIAN UNIVERSITY OF TECHNOLOGYInventors: Jiuchang He, Wei Zhang, Xiongfu Zhang, Dapeng Li, Ruimin Gao, Yongbin Lu, Shuqin Zhang, Mingfeng Wang, Pengju Huo, Si Li, Yuan Zhang, Zhiling Liu, Gang Chen, Ting Pei, Hua Zhang
