Adsorption properties of carbonized micron wood fiber filter for nanoparticles emitted by engine
摘要
Abstract
To effectively collect the nanosized particulate material (nanoparticles ) emitted by diesel, a diesel particulate filter(DPF) was prepared with carbonized micron wood fiber ( CMWF) material. The characteristics of CMWF filter and particulate material (PM) were analyzed to simulate the absorption process of nanoparticles in CMWF filter based on grand canonical ensemble Monte Carlo method (GCEMC). The numerical simulation result was verified by DPF performance test bench. The results show that when the pressure ranges from 102. 5 kPa to 125. 0 kPa at the temperature of 470 K, the adsorption number densities of nanoparticles in CMWF filter obtained by GCEMC and test are 6. 28 × 107 cm-3 and 5. 60 × 107 cm-3, respectively. The simulated results are in good consistency with the experimental results. The simulation method is suitable to investigate the adsorption process of nonoparticles in CMWF filter.关键词
