A comparison of coal flow and carbon emissions in Shanxi province between 2011 and 2016

Abstract

In order to explore the changes in coal flow and carbon emissions in Shanxi, a major coal-producing province during its transformation and up grading of the coal industry, based on coal balance tables of Shanxi province, the coal and carbon flow charts of 2011 and 2016 are drawn and compared.The results show:The coal de-stocking and the transfer of high-value-added coal products in Shanxi province have achieved remarkable results;technology of coal-to-liquids/gas has made breakthroughs, and the coal industry chain has been refined;solid waste and waste heat in the coal processing and conversion process have been resource utilized, and the heating efficiency has further increased, from 75.6% in 2011 to 80.2% in 2016;the increase of the total amount of coal-related carbon emission in Shanxi Province from 2011 to 2016 is small, and carbon emission in the power generation sector has been effectively controlled but that of heating sector has risen markedly;although carbon emission from domestic consumption has declined significantly, rural carbon emission is twice that of urban areas, and the rural areas are the key areas for carbon emission control in the future.The research results provide a direction for future coal production structure adjustment, coal processing technology improvement and coal-related carbon emission mitigation in Shanxi province, and have reference significance for other coal-dominated provinces facing the energy transformation.
