Abstract: In nature pyrolysis can bc considered as the initial stagc and/or paralleling part of coal
combustion, gasification and direct liquefaction, and pyrolysis itselt is also one of the fundamental
technologies in coal conversion processes. Thus it is understandable that reaction heat of coal pyrolysis
is of significancc that it is thc important thcrmodynamic paramctcr uscd in reactor dcsign, mcchanism
study, and cncrgy cfficicncy assessment. This papcr prcscnts a critical survcy on the status of mcthods
and icchniqucs for Icasurcmcnt of pyrolysis rcaction heat of coal and rclcvant hctcrogcncous organic
matters, and a detailed analysis and comparison of these methods, such as model prediction methods
(Merric model, Strezov model) and experimental measuring methods(heat value method, electricity
powcr mcthod, computcr aided thermal analysis, and differcntial scanning calorimctry method)wcrc
conducted, in which cspccial attcntion was paid to thc possibility of application of thcsc mcthods in thc
measurement of pyrolysis reaction heat. Results show that an easy, but rational and considerable
accurate method for measurement of coal pyrolysis heat on the basis of TG-DSC technique could be
cstablished under conditions that thc cffccts of mcasuring paramctcrs on mcasurcmcnt precision arc
thoroughly studicd and clucidatcd, as well as the mcasurcmcnt data resolution process is constructcd
