Abstract
The present invention relates to a method for removing sulphur dioxide from gaseous effluent, wherein a mixture of gaseous outlet gasses or gaseous effluent includes sulphur dioxide and carbon monoxide, and wherein, to perform a catalytic reduction, a catalyst is used to catalyse a reaction between carbon monoxide and sulphur dioxide to produce carbon dioxide and sulphur.
Claims24
The use of a Catalyst comprising at least 90% by weight of titanium dioxide to catalyse a reaction between carbon monoxide and sulphur dioxide to produce carbon dioxide and sulphur to remove sulphur dioxide from gaseous effluent.
4-35. (canceled)
A method for removing sulphur dioxide from gaseous effluent by performing a catalytic reduction:
- wherein the gaseous effluent includes sulphur dioxide and carbon monoxide, and
- wherein the catalytic reduction is performed using titanium dioxide to catalyse a reaction between carbon monoxide and sulphur dioxide to produce carbon dioxide and sulphur such that a majority of the carbon monoxide reacts.
A catalytic reactor for removing sulphur dioxide from an effluent gas mixture comprising:
- a) a reactor chamber having an inlet for receiving the effluent gas mixture and an outlet for expelling a gaseous mixture including the products of a catalytic reduction step;
- and
- b) a catalyst bed located within said reactor chamber comprising a catalyst comprising at least 90% by weight of titanium dioxide;
- wherein the effluent gas mixture comprises sulphur dioxide and carbon monoxide;
- and
- wherein the titanium dioxide catalyses a reaction between carbon monoxide and sulphur dioxide to produce carbon dioxide and sulphur.
