Abstract：In order to reduce CO2 emissions from coking in iron and steel enterprises,a calculation model of CO2 emissions was established based on material flow analysis. Based on the practical production data of one iron and steel enterprise,the sources and sink of carbon in coking were analyzed. The results showed that,the enterprise adopted 65 and 36 holes ovens,one ton coke production involved 986. 76 and 984. 87 kg carbon conversion respectively. Among them,about 80. 40% and 80. 65% carbon element transfered to coke,in other words,the effective utilization rate of carbon element was 80. 40% and 80. 65%,the rest carbon transfered to other products. Increasing coking cham-ber capacity,recycling coke oven gas,crude benzene and coal tar,adopting coal moisture technologies could decrease CO2 emissions.
