Production of Benzoic Acid through Catalytic Transformation of Renewable Lignocellulosic Biomass
《Chinese Journal of Chemical Physics》2017年第5期588-594,I0002,共8页张义恒 范明慧 常瑞 李全新 
In the present work, we reported a novel route for the conversion of lignocellulosic biomass (sawdust) to a high-value chemical of benzoic acid under atmospheric pressure. The trans- formation involved the catalytic...

Influence of Metallic Modification on Ethylbenzene Dealkylation over ZSM-5 Zeolites被引量:5
《Chinese Journal of Chemistry》2015年第2期247-252,共6页Chao Hu Junhui Li Wenzhi Jia Min Liu Zhixian Hao Zhirong Zhu 
supported by the National Natural Science Foundation of China(Nos.20873091,51174277);China National Petroleum Corporation Innovation Research Funds(No.2012D-5006-0505).
A series of metal-modified HZSM-5 catalysts were prepared by impregnation and were used for ethylbenzene dealkylation of the mixed C8 aromatics(ethylbenzene,m-xylene and o-xylene).The effects of different supported me...

Composition of substituents on pyrrole ring of high-carbon-number geoporphyrins and its dealkylation
《Chinese Science Bulletin》1999年第3期267-269,共3页ZHANG Chunming and LIN Renzi Geochemistry Research Center, Jianghan Petroleum Institute, Jingzhou 434102, China Department of Geoscience, University of Petroleum , Beijing 100083, China 
Geoporphyrins, isolated from source rock, were analyzed on electron ionization mass spectrometry (EIMS) and Tandem mass spectrometry (MS/MS). The spectrum of ElMS shows that the geoporphyrins are mainly composed o...
