    THE IMPROVEMENT OF QUALITY OF COAL USING

    Key words: separation, high gradient magnetic field, coal. 1. INTRODUCTION It is well known that coal contains compounds of the sulphur from which after burning is obtained SO2 very dangerous for pollution of atmosphere because may favors acid rains. The sulphur extant in ore of coal may be eliminating using a magnetic method of separation [1

    Pilot-scale studies of sulfur and ash removal from coals

    Abstract: This paper presents the results of pilot-scale studies of sulfur and ash removal from coal by high gradient magnetic separation (HGMS). Work was done on both the liquefied coal and the raw pulverized coal in water slurries. The effects of residence time, field intensity, packing material and density, slurry concentration and recycle on the grade and recovery of the wet separation of

    Dry separation essentially relies on separation of components based on some differences in the physical or surface properties of the components. These may be physical/mechanical, magnetic, or electrical. Mechanical separation may be effective down to 1mm particle size, while electrical and magnetic are most suitable below 1mm particle size

    Desulphurization of High Sulfur Coal by Mild Pyrolysis

    In this work, a new desulfurization process of high sulfur coal was designed and examined. The novel process involved pyrolysis of high sulfur coal at low temperature and then a dry magnetic separation. For testing the cleaning coal process, a Chinese high sulfur coal, Baisu coal was pyrolyzed in a fixed bed reactor from 400 to 700 C for 30min, and then separated by a dry magnetic separator
