Effect of Temperature-controlled conditions on the decomposition of particulate matter deposited in the diesel particulate filter channel by treatment with Non-thermal plasma

Efficient simultaneous removal of diesel particulate matter and hydrocarbons from diesel exhaust gas at low temperatures over Cu–CeO2/Al2O3 coupling with dielectric barrier discharge plasma

“…DPM samples were collected from the buffer tank (figure 1), and the oxidation properties in 10% O 2 atmosphere (Ar balance, 100 mL min -1 ) were analyzed using TG-MS. The T 10 , T 50 and T 90 values (the temperatures at which 10%, 50% and 90% of DPM were removed) are 290 °C, 628 °C and 700 °C, respectively (figure 2(a)), close to those of a DPM from a real diesel engine [37]. The main oxidation products of the DPM are CO 2 and CO (figure 2(b)), proving that the major component of DPM is carbon.…”
