Study on the catalytic pyrolysis of coal volatiles over ...

2020-10-1 · A hematite catalyst was used for pyrolysis tar upgrading. • Hematite A and B decreased the pitch content by 7.59 and 8.88 % respectively. • Catalytic pyrolysis of coal enhanced the content of Fe 2+ in hematite.. Fe and lattice oxygen were the decisive factors in the bond cleavage of heavy tar.

2021-4-1 · A model G400 FBRM particle size analyzer from Mettler Toledo was used to study the flocculation process of hematite and quartz with different reagents. For each flocculation study, 50 g of single mineral (hematite or quartz) was mixed with 500 mL water in a beaker of 500 mL, and stirred by a four-blade impeller with a speed of 300 rpm for 2 min ...

Data driven particle size estimation of hematite grinding ...

2019-1-25 · As a production quality index of hematite grinding process, particle size (PS) is hard to be measured in real time. To achieve the PS estimation, this paper proposes a novel data driven model of PS using stochastic configuration network (SCN) with robust technique, namely, robust SCN (RSCN). Firstly, this paper proves the universal approximation property of RSCN with weighted least squares ...

Oolitic Hematite | Scientific

Abstract: To enhance effective use of resources, we use magnetic separation method on the experiment study of a refractory oolitic hematite ore. Research showed that: the grade of raw ore (TFe) was 47.44%, and magnetic iron grade (MFe) was 28.59%. Through magnetic separation experiment, three-step magnetic separation process was chosen.
