Title:
METHOD FOR PYROLYSIS OF USED RUBBER AND RUBBER MATERIAL FOR PYROLYSIS
Document Type and Number:
WIPO Patent Application WO/2023/277171
Kind Code:
A1
Abstract:
The present invention provides a method for pyrolyzing used rubber, wherein the method exhibits an excellent yield of isoprene and limonene without reducing the pyrolysis efficiency. The method for pyrolyzing used rubber is characterized by carrying out pyrolysis after contacting or swelling the used rubber with a medium that has an SP value of 8.3-11 (cal/cm3)1/2, has an endothermic peak temperature, as measured by thermogravimetric analysis (TGA), of at least 235°C, and is liquid at 150°C.
