Abstract
Composition of gas from pyrolysis of Estonian oil shale with various sweep gases
Highlights
Compared with other energy sources such as coal and biomass, oil shale is considered to have great potential due to its large known deposits [1]
The Fischer assay method was used to analyze the pyrolysis of Estonian kukersite oil shale with CO2, CO2/steam, N2 and N2/steam sweep gases
This research focused on the gaseous products of the pyrolysis of Estonian kukersite oil shale by using the Fischer assay method
Summary
Compared with other energy sources such as coal and biomass, oil shale is considered to have great potential due to its large known deposits [1]. The oil shalebased energy production has been acquiring importance in several countries. Studying various aspects of the processing of oil shale would be helpful to assess and mitigate the environmental risks [6]. In light of these reasons, investigating alternative fuels has raised interest among researchers and abundant analysis has been done on shale oil derived from oil shale pyrolysis. The yields and concentrations of pyrolysis gases are important parameters to learn about the quality of the shale gas produced. Since the decomposition of kerogen and conversion to oil take place mainly at temperatures below 500 °C, studying the evolution of gas gives more information about its composition as well as the mechanism of the decomposition process. The results give evidence of the dependency of the release of the gases on temperature
