Filtration characteristics with parameter variation for dust removal from syngas

•The better removal efficiency was obtained under a test temperature of 600 °C, a gas velocity of 50 cm/s and a movement velocity of silica sand of 1.95 mm/s.•With higher movement velocity of silica sand, higher of k1 and k2 caused better performance of inertial impaction, thereby enhancing the removal efficiency.•The results of this study was improved the operation performance of system for gas cleaning at high temperatures.
