EMPIRICAL CORRELATIONS FOR BIOMASS PYROLYSIS PREDICTIONS

摘要

This work provides literature data on the characteristics of biomass pyrolysis. It is analyzed thernbehavior of product yields and properties on pyrolysis peak temperature dependence (within 200-1000oC). Empiricalrnrelationships are derived from the collected data, which can be used to approximate the elemental composition andrnheating value of chars, tars and total permanent gas as well as yields of carbon monoxide, hydrogen and lightrnhydrocarbons. Some of these relationships seem valid for almost any biomass and are roughly independent of thernpyrolysis conditions. Since pyrolysis is a common stage on the thermo-chemical conversion of solid biomass, therninformation provided here can be applied in the scope of pyrolysis, gasification and combustion applications.
