焙烧条件对FCC催化剂孔体积和表观松密度的影响

Effect of Calcination Condition on Pore Volume & Apparent Bulk Density of FCC Catalyst

研究了焙烧条件对FCC催化剂孔体积和表观松密度的影响,结果表明,在480～650℃范围内,随着焙烧温度的升高,FCC催化剂孔体积增大,FCC催化剂在650℃焙烧2h的孔体积比在480℃焙烧2h的孔体积增加0.03mL·g-1;在480～650℃范围内,随着焙烧温度的升高,FCC催化剂表观松密度略有增加,FCC催化剂在650℃焙烧2h的表观松密度比在480℃焙烧2h的表观松密度增加0.01 g·mL-1.

Effect of calcination condition on pore volume & apparent bulk density of FCC catalyst was studied.The results showed that pore volume of FCC catalyst increase with calcination temperature.Pore volume of FCC catalyst calcinated at 650℃ for 2 hours is 0.03mL·g-1 more than that calcinated at 480℃.FCC catalyst calcinated at higher temperature become a little denser.Apparent bulk density of FCC catalyst calcinated at 650℃ for 2 hours is 0.01 g·mL-1 more than that calcinated at 480℃.
