difference in the pressure drop 关于催化剂的问题？ the effect of packing on pressure drop is very marked. to a first approximation the pressure drop is inversely proportional to the cube of the voidage. thus the difference in the pressure drop between loosely packed bed and a closely packed bed is roughly in the ratio 0.93 to 11 m3, or about 1.0 to 1.4. a loosely packed bed will settle in use, and the pressure drop may increase by up to 50% as this occurs. 催化剂的装填对床层压降的作用是明显的，粗略地讲床层压降与装填的催化剂之间空隙之体积立方数成反比，松散装填与密堆装填的产生的床层压降的差值大约为0.93 ：1.1 /m3,或1：1.4。取松散装填，此时，床层压降会增加50%。 按字面翻译，催化剂装填越松散，床层压降应越小呀，即减少50%，不应是增加50%呀，实际生产中也应是如此呀。文中increase是否应是decrease呀？查看更多
