Gaseous non-methane hydrocarbons(NMHC) emission from petrochemical industry and its remediation strategy

Carbon isotope features of alkane gases in the coal measures of the Xujiahe Formation in the Sichuan Basin and their significance to gas-source correlation

The carbon isotope distribution pattern of alkane gases can be divided into three types: normal carbon isotopic distribution characterized by organic genetic alkane gas; negative carbon isotopic distribution characterized by inorganic alkane gas; reversal trend of alkane gas carbon isotope characterized by secondary modified gas.

Based on the characteristics of the pre-reforming processes of gaseous hydrocarbons,the preparation of nickel based pre-reforming catalyst CN-30 was proposed.

The purpose of this study is to reveal the composition and carbon isotopic variation of gaseous hydrocarbon including methane, ethane and propane by combining the kinetic simulating experiment of pure n-C_18H_38 and the GC-IRMS analysis of methane, ethane and propane in the pyrolysates.

At the mature stage of organic matter, the total gas yield of marl was above that of shale, and their total gaseous hydrocarbon yield was approximately the same.

After contrasting and analyzing the results of liquid hydrocarbon and gaseous hydrocarbon productivity and component from hydrous pyrolysis of two typical immature samples of black mudstone,it is discovered that their differences are still remarkable.
