Title:
METHOD FOR CONVERTING PLASTIC INTO OIL AND APPARATUS FOR CONVERTING PLASTIC INTO OIL
Document Type and Number:
WIPO Patent Application WO/2022/254734
Kind Code:
A1
Abstract:
The purpose of the present invention is to efficiently decrease the molecular weight of a thermal decomposition gas with use of a small amount of a ceramic catalyst, the thermal decomposition gas being generated from a thermally decomposed plastic. According to the present invention, a thermal decomposition gas generated from a thermally decomposed plastic is brought into contact with an alumina silicate catalyst at an ambient temperature of 350°C to 400°C and is subsequently brought into contact with a silica alumina catalyst in a catalyst tank so as to decrease the molecular weight of the thermal decomposition gas. The alumina silicate catalyst is in the form of a sphere or an oval sphere, while having a ratio of silicic acid to alumina of 0.8-1.2:1 and a volume of around 10 to 30 mm3; and the silica alumina catalyst has a long and thin shape with a diameter of around 1 mm, while having a ratio of silica to alumina of 1.4-1.6:1 and a volume of around 1 to 10 mm3.
