Catalytic Pyrolysis of Waste Flat-Panel Display Plastics for Valuable Hydrocarbons
Original language description
Catalytic pyrolysis of waste flat-panel display (FPD) plastics and pure polystyrene (PS), which is the main polymer component in FPD waste, is conducted at 500 degrees C in a micropyrolysis reactor to enhance benzene, toluene, ethylbenzene, and xylene (BTEX) production and eliminate styrene and heteroatom compounds in pyrolysis products. A comparative study with PS reveals similar product distributions, indicating that FPD waste additives do not significantly impede the catalytic reactions. Zeolitic catalysts (HZSM-5, H beta, and HY) effectively reduce nitrogen- and oxygen-containing compounds and also styrene with increase in BTEX and polycyclic aromatic hydrocarbons (PAHs) yields. Even at a feed:catalyst ratio of 1:1, distinct product distributions are observed compared to the noncatalytic run. In the presence of H beta, benzene is the main compound, exhibiting a 22% increase. With HY, ethylbenzene is the dominant product, showing a 36% increase. Notably, HY, which possesses the highest concentration of Br & oslash, nsted acid sites with minimum of Lewis acid sites together with the largest pore size among the studied zeolites, preferentially enhances the formation of ethylbenzene within the BTEX.
