Реферат:
The experimental studies and mathematical modeling are presented for the residence time distribution of fine solids moving in a co-current downflow fixed-bed reactor. Experiments were carried at ambient conditions using a glass column of 30 mm i.d. packed by spheres of 4–6 mm diameter. Fine alumina of 50–250 μm was used as a moving solids. Solids flow rate was varied from 0.1 to 0.5 g cm−2 s−1. The new flight-time technique is applied to measure residence time of fine particles in a packed bed. The influence of particle size and flow rate on the particles residence time is experimentally investigated. New three-dimensional model of moving of fine particles in a packed bed is developed. The model is based on the statistical calculations of an individual particle path in a packed column. Model validation was checked by comparing experimental values of particles residence time distribution with calculated one. Calculated values of particles residence time were found to be in a good agreement with experimental data at the solids flow rate below 0.1 g cm−2 s−1.
