STUDY ON COMPRESSIVE STRENGTH OF COKE AFTER GASIFIED WITH CO_2 AND STEAM

摘要

By the coke gasified reaction device and online measurement high-temperature compressive strength apparatus, the variation of pore structures of coke after gasified reaction with CO_2 and H_2O was investigated. Research illuminating the influences of solution loss rate, temperature, and carbon species on compressive strength of coke was also carried out. The results showed that the total compressive strength was higher than for the reaction with CO_2. The high-temperature compressive strength of coke decreased with the increasing of solution loss ratio or temperature after reacting with CO_2 and H_2O. At the same solution loss ratio, the damage of pore structure to coke strength after gasified reaction with H_2O was relatively smaller and the deformation resistance was stronger when compared with that in CO_2.
