The pyrolysis behavior of hemp pulp cigarette paper was investigated via thermal gravimetric analysis(TGA) and pyrolysis gas chromatography-mass spectrometry(PyGC/MS).In helium atmosphere,the compound was pyrolyzed at 400,500,600,700,800,and 900℃,respective.y.The pyrolysis products were directly introduced into GC/MS with 1.03×106 Pa He and were qualitatively and semi-quantitatively analyzed.The results show that different pyrolysis temperatures directly impact on the type of and relative contents the pyrolysis products.At the seven pyrolysis temperatures mentioned above,complex pyrolysis products were formed and 156 products were detected altogether,including 1-methyl-1,3-cyclopentadiene,2-methylfuran,2,3-dihydrobenzofuran,benzene,and toluene.Moreover,at low temperatures,the main pyrolysis products were alkenes,furans,and ketones.With the elevation of the pyrolysis temperature,the contents of alkenes and ketones decreased,and the contents of benzene,benzene derivatives,and PAHs(polycyclic aromatic hydrocarbons) increased gradually.The contents of harmful pyrolysis products of the cigarette paper can be reduced by reducing the cigarette combustion temperature.If only the impact of hemp pulp cigarette paper is considered,the best combustion temperature of cigarette should be controlled at 500℃.
