Research on the influential factors of floatation desulphurization of coal by microbe;

Through the laboratory and industrial tests,SX-JLF-40-3 jet flow flash flotation machines are used in iron concentrate desulfurization flotation instead of XJK-2.

This article introduces the EH-3 medium-temperature sulfur-resistant hydrolyst and ambient-temperature fine desulfurization and their application in Texaco water gas.

This paper collected fine desulfurization technique patent technique at ambiant temperature at in the last decade,classifiedly listed it's physico-chemical properties and several fine desulfurization technique at ambiant,finally set forth it's merities,demerities and the furure development.

The performance of QSJ-01 type carbonyl sulfide hydrolysis catalyst and QTS-01 type ambient temperature desulfurizer for ambient temperature fine desulfurization of propylene was studied and their lateral line tests was outlined.

The features and desulfurizing principle of fine desulfurizer at ambient temperature were introduced.

The loading metal oxide desulfurizer was prepared by impregnating-depositing on the support of γ-Al2O3, the fine desulfurizer of metal oxide with high dispersion and equality was also prepared by adding competing sorbent.

EF-2 special ferric oxide fine desulfurizer,used in ambient temperature,was prepared by the impregnated method .
