Narrow-pore-size-distribution and large-size cordierite gasoline particle filter and preparation method thereof
The invention discloses a narrow-pore-size-distribution and large-size cordierite gasoline particle filter. In micropore apertures of the cordierite gasoline particle filter, D10 is larger than or equal to 7 micrometers, D90 is smaller than or equal to 50 micrometers, the pore distribution coefficient K is equal to (D90-D10)/D50 and smaller than or equal to 3.0, and the cordierite gasoline particle filter is prepared from 50.5%-51.1% of hollow silicon dioxide microspheres, 35.2%-35.8% of flaky alpha aluminum oxide and 13.4-14.0% of active magnesium oxide. The hollow silicon dioxide microsphereis of a hollow orifice shell structure, the thickness of the shell wall is 0.2-1.0 [mu]m, D50 is equal to 20-36 [mu]m, D10 is larger than or equal to 15 [mu]m, D90 is smaller than or equal to 47 [mu]m, and the particle size distribution coefficient P is equal to (D90-D10)/D50 and smaller than or equal to 1.3. The prepared cordierite gasoline particle filter with narrow pore size distribution andlarge size meets the PN emission requirement without pretreatment.
本发明公开一种窄孔径分布、大尺寸堇青石汽油颗粒过滤器，堇青石汽油颗粒过滤器中的微孔孔径中，D10≥7微米，D90≤50μm，孔分布系数K＝(D90‑D10)/D50≤3.0，堇青石汽油颗粒过滤器由50.5％‑51.1％的空心二氧化硅微球、35.2％‑35.8％的片状α氧化铝、13.4‑14.0％的活性氧化镁的制成，空心二氧化硅微球为中空窍壳结构，壳壁厚度为0.2‑1.0μm，其D50＝20‑36μm，D10≥15μm，D90≤47μm，粒度分布系数P＝(D90‑D10)/D50≤1.3。本发明制得的窄孔径分布、大尺寸堇青石汽油颗粒过滤器满足了不用预处理就满足PN排放的要求。
