硕士生答辩：Mr. Sun, Mr. Dong and Miss Dong successfully defended their Master theses
On June 3, 2020, Mr. Jie Sun, Mr. Guo-hua Dong and Miss Qian Dong supervised by Prof. Zhen Fang, successfully defended their theses in A302 Huixia Building, Pukou Campus of Nanjing Agricultural University. The defending committee was composed of Prof. Chun-xia He (chair) from Nanjing Agricultural University, Prof. Hong-mei Jin from Jiangsu Provincial Academy of Agricultural Sciences, associate Prof. Xiao-yu Yong from Nanjing Technology University and associate Prof. Yu-tao Liu from Nanjing Agricultural University.
Mr. Sun, Mr. Dong and Miss Dong presented their research results for Master theses, the committee members raised relevant questions. Based on the replies and theses reviewed, the panel agreed that the three students had successfully completed their research and course requirements on agricultural bio-environment and energy engineering. Mr. Sun studied the hydrothermal gasification of agricultural wastes in subcritical water system with his thesis entitled “Catalytic gasification of lignocellulosic wastes with Ni-Co bimetallic catalysts in subcritical water”. Mr. Dong studied the gasification of cooking wastes with Ni-BN/Al2O3 in subcritical water to produce hydrogen with his thesis entitled “Subcritical hydrothermal gasification of cooking wastes with Ni-BN/Al2O3 catalyst to produce hydrogen rich gas”. He selected the process conditions for producing hydrogen from cooking waste and achieved the gasification of cooking wastes. Miss Dong studied the pretreatment of cotton stalk with ethylene glycol-chloride salts with her thesis of “Study on enzymatic hydrolysis and saccharification of cotton straw pretreated with ethylene glycol-chloride salts”. She optimized the pretreatment conditions and achieved the cotton stalk efficient saccharification. As first author, Mr. Sun published 1 Journal paper (Q1) and filed 1 invention patent. Mr. Dong co-authored 3 papers and Miss Dong co-authored 6 papers.
After the jury voted by secret ballot, the panel agree to confer Master of Science in Engineering Degree to Mr. Jie Sun, Master of Engineering Degrees to Mr. Guo-hua Dong and Miss Qian Dong, respectively subjected to the approval by the Academic Degrees Committees of the college and university.
.
Congratulations to Mr. Sun, Mr. Dong and Miss Dong!
2020年6月3日下午，南京农业大学生物能源组2017级工学硕士研究生孙杰（男），2018级工程硕士研究生董国华（男）和董倩（女）毕业答辩会在南京农业大学浦口校区汇贤楼A302举行。南京农业大学的何春霞教授担任答辩评审委员会主席，江苏省农科院的靳红梅研究员，南京工业大学的雍晓雨副教授和南京农业大学的刘玉涛副教授共三位专家担任评审委员。
答辩会上，孙杰，董国华和董倩三位同学分别对各自在校期间学位论文进行汇报，同时答辩委员会主席和各位评委提出了相关问题。根据三位同学问答问题以及学位论文评阅基础上，经过评审决议，专家组一致认为孙杰，董国华和董倩同学顺利完成了农业生物环境与能源方面的研究和学习要求。孙杰同学在毕业论文《亚临界水体系下Ni-Co双金属催化剂对木质纤维素废弃物催化气化研究》中研究了在亚临界水体系下Ni-Co双金属催化剂催化农业废弃物气化，并针对气化的工艺条件进行了筛选，可以达到气化农业废弃物的效果。董国华同学在毕业论文《Ni-BN/Al2O3催化餐厨垃圾亚临界水热制氢的研究》中研究了Ni-BN/Al2O3在亚临界水中催化餐厨垃圾制氢，针对餐厨垃圾在亚临界水中制氢的工艺条件进行了研究，实现了餐厨垃圾的气化。董倩同学在毕业论文《乙二醇-氯化盐预处理棉花秸秆促进酶解糖化的研究》中研究了乙二醇-氯化盐对棉杆的预处理工艺，针对乙二醇-氯化铁预处理条件进行了优化，实现了棉杆的高效酶解糖化。三位同学在校期间工作努力，其中孙杰同学以第一作者发表Q1区论文1篇，受理专利1项；董国华同学参与发表论文3篇；董倩同学参与发表论文6篇。经评委会无记名投票表决，一致同意通过毕业答辩。
祝贺孙杰、董国华、董倩同学！
