Influence of Particle Size Distribution of Wood Waste Pyrolysis Product on Productivity and Purification Efficiency

Abstract:

In this paper, studies were carried out on sorption purification under dynamic conditions of a copper (II) ions model solution with sorption material. Sorption material was obtained by low-temperature pyrolysis from wood wastes. Studies were carried out for fractions with particle sizes less than 0.5 mm, 0.5-1 mm, 1-2 mm, 2 and more mm. Test model solution was a polydisperse system with particle sizes from 145 to 224 nm and 6450 to 8640 nm. Particle size of disperse phase of filtrate after passing through sorption material with particle size of 1-2 mm was in the range from 310 to 412 nm and from 2260 to 3300 nm. Peaks of particle size intensity in the filtrate after passing through the sorbent (fraction 1-2 mm) were shifted downward. This indicates that smaller particles remained in the filtrate after purification. This is confirmed by an increase in the sorption rate of copper ions. As the particle size increases, the filtration rate increases, but the efficiency of removing copper ions decreases. The degree of sorption of copper ions from the model solution with an initial concentration of 1028 mg/dm³ was 96.4% for the fraction of the pyrolysis product with a particle size of 1-2 mm, 91.9% - less than 0.5 mm, 91.1% - 0.5-1 mm, 91.7% - more than 2 mm.
