Abstract
The inventive technology includes methods and apparatus for the generation and application of segregated catalytic additives for the pre-combustion treatment of carbonaceous fuel and/or feedstocks. The application of such segregated additives results in the reduction of environmentally harmful emissions during combustion as well as gasification processes. Specifically, pre-combustion treatment of carbonaceous materials with the inventive additives results in the reduction of NOx and/or mercury emissions by least 20% and 40% respectively.
Claims29
A method of catalyzing the gasification of carbonaceous feedstock comprising the steps of:
- segregating a quantity of particulate matter source compound to an ultra-fine particle size;
- segregating a quantity of calcium source compound to an ultra-fine particle size;
- milling at least one carbonaceous feedstock in the presence of said segregated particulate matter source compound and said segregated calcium source compound to form a catalytically enhanced carbonaceous feedstock;
- processing said catalytically enhanced carbonaceous feedstock in a gasification reactor;
- and
- gasifying said catalytically enhanced carbonaceous feedstock to produce select product gas components wherein said step of gasification results in production of select product gas components having catalytically decreased contaminants than gasification without said catalytically enhanced carbonaceous feedstock.
A method of catalyzing the gasification of carbonaceous feedstock comprising the steps of:
- segregating a quantity of particulate matter source compound to an ultra-fine particle size;
- segregating a quantity of calcium source compound to an ultra-fine particle size;
- milling at least one carbonaceous feedstock in the presence of said segregated particulate matter source compound and said segregated calcium source compound to form a catalytically enhanced carbonaceous feedstock;
- processing said catalytically enhanced carbonaceous feedstock in a gasification reactor;
- and
- gasifying said catalytically enhanced carbonaceous feedstock wherein said step of gasification results in catalytically increased yield of select product gas components than gasification without said catalytically enhanced carbonaceous feedstock.
A method of generating a catalytically enhanced carbonaceous feedstock comprising the steps of:
- capturing a quantity of particulate matter source compound from the combustion of a carbonaceous fuel;
- segregating said quantity of said captured particulate matter source compound to an ultra-fine particle size;
- establishing a quantity of calcium source compound;
- segregating said quantity of calcium source compound to an ultra-fine particle size;
- milling at least one carbonaceous feedstock in the presence of said segregated particulate matter source compound and said segregated calcium source compound to form a catalytically enhanced carbonaceous feedstock.
