Reaction behavior of oil sand in fluidized-bed pyrolysis

Petroleum Science 2013年第4期10卷 562-570页

作者： Gao Jinsen Xu Tao Wang Gang Zhang Angui Xu Chunming State Key Laboratory of Heavy Oil Processing China University of Petroleum China International United Petroleum & Chemicals Co. Ltd.

The reaction behavior of oil sand from Inner Mongolia（China） were studied in a fluidizedbed pyrolysis process,and a comparative study was conducted on the properties of the liquid products obtained through fluidized-bed pyrolysis of oil sand and the native bitumen obtained by solvent *** results indicated that the fluidized-bed pyrolysis,a feasible carbon rejection process,can be used to upgrade oil *** reaction temperature and time were found to be the key operating parameters affecting the product distribution and yields in fluidized-bed pyrolysis of oil *** optimal temperature was 490℃ and the most suitable reaction time was 5 *** these operation conditions,the maximum yield of liquid product was 80wt%.In addition,the pyrolysis kinetics of oil sand at different heating rates of 5,10,20 and 30℃/min was investigated using a thermogravimetric analyzer（TGA）.

Journal of Coal Science & Engineering(China) 2000年第1期6卷 57-62页

作者：程军周俊虎曹欣玉岑可法 Zhejiang University Hangzhou310027

The combustion characteristics of lignite blends were studied with a thermogravimetric analyzer (t g a.), at constant heating *** characteristic temperatures were determined from the burning *** was found that the characteristic times of combustion reaction moved forward, the ignition temperature dropped and the burnout efficiency slightly changed when blending *** characteristic parameters of blends could not be predicted as a linear function of the average values of the individual *** blending with less reactive coal, the ignition and burnout characteristics of lignite turned worse.

The objective of this paper focuses on the thermal decomposition process in modified aromatic amine-based *** thermal decomposition of a serial of special modified aromatic amine-based polybenzoxazines is conducted by the thermogravimetric analyzer (TGA),the derivative thermogravimetry(DTG) and the cone *** results show that there are one or two main stages during the thermal decomposition process in modified aromatic amine-based *** main reaction heat comes from the low temperature stage lower than 450℃.The heat from the high temperature higher than 450℃is not as much as the low temperature stage. Cone calorimeter is an instrument to give the data for HRR,EHC,MLS,SEA and so oa It also provides evidence to collect the thermal decomposition products such as CO,CO,smoke and oxygen consumed in this *** thermal decomposition process of modified system strongly depends on the molecule structure of main composition in modified aromatic amine-based *** thermal stability of modified aromatic amine-based polybenzoxazines is excellent due to the molecule structure of aromatic amine in modified polybenzoxazines.
