Study on Heat Release Behavior of Pinus Biomass by TD-GC-MS
Pinus has been put into mass production. However, many heat release volatiles would produce air pollution during drying process. Therefore, the heat release behavior of Pinus biomass was studied by TD-GC/MS. The main constituents were at 100°С 1,4-methanoazulene,decahydro-4,8, 8-trimethyl-9-methylene-(30.6%), 1,4-methanoazulen-9-ol,decahydro-1,5,5,8a-tetramethyl-(14.85%), 1,2,4-methenoazulene, decahydro-1,5,5,8a-tetramethyl-(8.56%), 1r-.alpha.-pinene(7.92%), epiglobulol(4.57%), bicyclo[2.2.1]heptan- 2-one, 1,7,7- trimethyl-, (1r)- (4.33%), caryophyllene oxide(3.37%), etc. And the main constituents at 110°С were 1,4-methanoazulene, decahydro-4,8, 8-trimethyl-9-methylene-(40.31%), 1,4-methanoazulen-9-ol, decahydro-1,5,5,8a-tetramethyl-(15.35%), .alpha.-pinene(8.88%), bicyclo [2.2.1]heptan-2-one, 1,7,7- trimethyl-, (1r)- (5.73%), cyclohexane-1,3-dione, 2-allylamin omethylene-5,5-dimethyl-(5.24%), naphthalene, 1,1'-(1,2-ethanediyl) bis[decahydro-(4.83%), spiro[5.5]undec-2-ene,3,7,7-trime thyl-11-methylene-(4.05%), etc. The heat release volatiles of Pinus biomass was safe to people during drying process.
