玉米秸秆与塑料PE共气化过程中碱金属迁移行为的研究
Study on migration behavior of alkali metals during co-gasification of corn stalk and PE
摘要
Abstract
The migration behavior of alkali metals during co-gasification of cornstalk and PE in a fixed bed at different temperatures was studied on the thermodynamic equilibrium calculation,the X-ray power diffraction and scanning electron microscope/energy dispersive spectrometer.The results indicat that the alkali chlorides (KCl、K2Cl2 、NaCl)are the main components in gaseous.There is a large amounts of C and H in the fules with the mixed of plastic PE.The H makes the C1 prefer HC1 to KC1,meanwhile,the release radio of K is lower than the cornstalk gasification cause of the C easily reacted with K than Na.Alkali metal compounds in ashes are mainly in the forms of KCl,NaCl,K2SO4,KAlSi3O8,KAlSiO4,NaAlSi3O8,NaAlSiO4.The KCl,NaC1 begin to release when the reacting temperature above 800 ℃ and most of K,Na,Cl are easily deposited on the edge of the hole.关键词
