Contrastive Analysis on Low Temperature Carbonization of Longkou and Yaojie Oil Shale in Aluminum Retort

Abstract:

Lots of basic analyses carried on YJOS (Yaojie oil shale) and LKOS (Longkou oil shale) consist of proximate analysis, ultimate analysis, XRF analysis and shale oil yield in aluminum retort. Besides, TGA are used on YJOS, LKOS and shale oil, gas chromatographic analysis is used on retorting gas. The results show that LKOS and YJOS have the same hydrogen-to-carbon ratio, but LKOS has higher volatile component and its oil yield in aluminum retort is much higher than YJOS. Ca content in LKOS is much higher than YJOS, however, Al and Fe content in LKOS are lower than YJOS. Two kinds of shale oil after destructive distillation have similar composition and relative content, in addition, they all produce more low boiling point distillates, combustible component of their destructive distillation gas are H₂ and CH₄, the second are CO and C₂H₆. Aluminium retort experimental findings, The carbonization temperature is the main influence factor on oil shale destructive distillation process in aluminum retort. Residence time has small influence on shale oil yield but need to choose appropriate heating rate and particle size. Best carbonization parameters of LKOS in aluminum retort: Temperature 500~550°C, heating rate 5°C/min, particle size 2~4mm, Residence time 10~20min;the best parameters of YJOS: Temperature 500~550°C, heating rate 5°C/min, particle size0.2~0.9mm, residence time 10~20min.
