Abstract
ABSTRACTPyrolysis of pressure-sensitive adhesive (PSA) wastes have been investigated in a fixed-bed reactor with a heating rate of 20°C/min. PSA pyrolysis mainly occurs between 300 and 600°C. The maximum liquid yield was obtained at 550°C with a yield of 55.69%. Liquid product can be used as fuel or raw material for purifying 2-ethyl-1-hexanol, dehydroabietic acid, 2,4-dimethyl-1-heptene, and styrene. The main composition in gas is CO and CO2, followed by CH4 and H2. High content of ash in char limits the application in fuel, but might be used as an adsorption material after upgrading.
