Abstract
The present description relates to a method and system for generating a fuel pellet from high sulfur fuel waste materials having a reduced SO2 emission. In one example, the fuel pellet may include petroleum coke, a biomass constituent, and an alkali substituent. Further in another example, the fuel pellet may include iron oxide catalyst increasing the capture of SO2.
Claims20
A fuel pellet comprising:
- petroleum coke, having a sulfur content up to 5.5%;
- a biomass constituent;
- an alkali constituent adapted to capture SO2 emissions by reacting with sulfur of the petroleum coke upon burn of the pellet;
- and
- an iron oxide catalyst reducing SO2 emissions to less than 10 percent;
- wherein the petroleum coke, the biomass constituent, the alkali constituent, and the iron oxide catalyst are combined to form a fuel pellet with decreased SO2 emission at temperatures at or above 750 C.
3 more elements
A fuel pellet comprising:
- petroleum coke, having a sulfur content up to 5.5%;
- a biomass constituent to provide volatiles;
- an SO2 sorbent to capture SO2 emissions upon burn of the pellet;
- and
- Fe2O3 as a catalyst reducing SO2 emission in comparison to the fuel pellet without addition of Fe2O3;
- wherein the petroleum coke, the biomass constituent, the SO2 sorbent, and the Fe2O3 are combined to form a fuel pellet with maximized BTU value and reduced SO2 emission at temperatures at or above 750 C.
3 more elements
A fuel pellet comprising:
- petroleum coke in the range of 50-90 percent by weight of the fuel pellet;
- wood waste in the range of 10 to 50 percent by weight of the fuel pellet;
- Ca(OH)2 in the range of 1 to 30 percent by weight of the fuel pellet;
- and
- Fe2O3 in the range of 2 to 4 percent by weight of the fuel pellet.
