| Abstract: | Catalyst particle size was rapid analyzed by laser particle size instrument, the laser beam was used to dif- fract on the sample particle in the sample pool, the scattering angle and particle size was inversely proportional, the inten- sity of scattered light was proportional to the particle concentration, and all measurement was analyzed and calculated by computer. This analysis method had the advantage of high speed, wide measuring range, simple operations and fast, and can very good to meet the needs of various catalvsts and dust oarticl~ ~i~,~ ~n~lwi~ |
