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 .

Industrial side-stream experiment of a fine SQ105 desulfurizer;

A wide temperature range zinc oxide fine desulfurizer EZ-2 and its industrial application in protecting methanation catalyst,natural gas steam reforming catalyst and propylene polymerization catalyst were described.

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.
