Study on Hydrophobic Microorganism as Coal Bio-Desulfurizing Agent

Abstract

Mycobacterium phlei belongs to protozoa,it is innocuous and it doesnt have any pathogenicity to all animals.Base on research of the biologic character of the hydrophobic microorganism and analysis of the FTIR spectrum and so on.Experiment results indicated that the surface of Mycobacterium phlei contains cyclanes,alicyclic hydrocarbon,aromatic nucleus and many kinds of organic function group and ionizing group so it was highly hydrophobic and highly charge.Because of this special biology surface character,Mycobacterium phlei may selective adsorption on the surface of coal and make coal form flock,and meanwhile effectually get rid of pyritic sulfur in coal.The Experimental effect of the Mycobacterium phlei on the getting rid of pyretic in the coal was obvious.The maximum pyrite desulphurization rate was reach to 72.63%,but the desulphurization percentage of organic sulfur was lower.The desulphurization rate was only 18.91%.
