Components derived from processed MSW waste streams can be used to make such feed stocks which are substantially free of glass, metals, grit and noncombustibles and contain a sorbent. These feed stocks are useful for a variety of purposes including as gasification and combustion fuels. In addition, one or more sorbents can be added to the feed stocks in order to reduce the amount of a variety of pollutants present in traditional fuel and feed stocks, including, but not limited, sulfur and chlorine. Further, these feed stocks with added sorbent can mitigate corrosion, improve fuel conversion, extend power generating plant lifetime, reduce ash slagging, and reduced operating temperature. ## Claims ### Claim 1 An engineered fuel feed stock comprising: plastic components and fiber components separated from an MSW stream having an HHV of between about 3,000 BTU/lb and about 8,000 BTU/lb; a carbon content of between about 30 wt. % and about 80 wt. %; and a hydrogen content of between about 3 wt. % and about 10 wt. %, and a sorbent, the engineered fuel feed stock having a sorbent content of between about 0.1% (w/w) and 50% (w/w), wherein the engineered fuel feed stock contains substantially no glass, metals, grit, and noncombustible waste. ### Claim 2 (depends on 1) The engineered fuel feed stock of claim 1, wherein the sorbent is selected from the group consisting of sodium sesquicarbonate (Trona), sodium bicarbonate, sodium carbonate, zinc ferrite, zinc copper ferrite, zinc titanate, copper ferrite aluminate, copper aluminate, copper manganese oxide, nickel supported on alumina, zinc oxide, iron oxide, copper, copper (I) oxide, copper (II) oxide, limestone, lime, Fe, FeO, Fe2O3, Fe3O4, iron filings, CaCO3, Ca(OH)2, CaCO3.MgO, silica, alumina, china clay, kaolinite, bauxite, emathlite, attapulgite, coal ash, egg shells, and Ca-montmorillonite. ### Claim 3 (depends on 1) The engineered fuel feed stock of claim 1, wherein the HHV is between about 5,000 BTU/lb and about 8,000 BTU/lb. ### Claim 4 (depends on 1) The engineered fuel feed stock of claim 1, wherein the engineered fuel feed stock has a moisture content of less than about 30 wt. %. ### Claim 5 (depends on 4) The engineered fuel feed stock of claim 4, wherein the moisture content is between about 10 wt. % and about 30 wt. %. ### Claim 6 (depends on 1) The engineered fuel feed stock of claim 1, wherein the engineered fuel feed stock has a volatile matter content of between about 40 wt. % and about 80 wt. %. ### Claim 7 (depends on 1) The engineered fuel feed stock of claim 1, wherein the engineered fuel feed stock has a sulfur content of less than about 2 wt. %. ### Claim 8 (depends on 1) The engineered fuel feed stock of claim 1, wherein the engineered fuel feed stock has a chlorine content of less than about 1 wt. %. ### Claim 9 (depends on 1) The engineered fuel feed stock of claim 1, wherein the MSW stream contains biodegradable and non-biodegradable wastes. ### Claim 10 (depends on 1) The engineered fuel feed stock of claim 1, wherein the hydrogen content is between about 6 wt. % and about 9 wt. %. ### Claim 11 (depends on 1) The engineered fuel feed stock of claim 1, wherein the carbon content is between about 40 wt. % and about 50 wt. %. ### Claim 12 (depends on 1) The engineered fuel feed stock of claim 1, wherein the engineered fuel feed stock has an ash content of less than about 10 wt. %. ### Claim 13 (depends on 1) The engineered fuel feed stock of claim 1, wherein the engineered fuel feed stock has an H/C ratio of between about 0.08 (w/w) and about 0.15 (w/w). ### Claim 14 (depends on 1) The engineered fuel feed stock of claim 1, wherein the engineered fuel feed stock has an O/C ratio of between about 0.01 (w/w) and about 1.0 (w/w). ### Claim 15 (depends on 14) The engineered fuel feed stock of claim 14, wherein the engineered fuel feed stock has an O/C ratio of between about 0.6 (w/w) and about 1.0 (w/w). ### Claim 16 An engineered fuel teed stock, comprising at least one component derived from an MSW stream, the engineered fuel feed stock comprising: an HHV of between about 3,000 BTU/lb and about 8,000 BTU/lb; a moisture content of between about 10 wt. % and about 30 wt. %; a carbon content of between about 30 wt. % and about 80 wt. %; a hydrogen content of between about 3 wt. % and about 10 wt. %; an O/C ratio of between about 0.6 (w/w) and about 1.0 (w/w); an H/C ratio of between about 0.08 (w/w) and about 0.15 (w/w); a sorbent, the engineered fuel feed stock having a sorbent content of between about 0.1% (w/w) and 50% (w/w), and wherein the MSW stream contains biodegradable and non-biodegradable waste and the engineered fuel feed stock contains substantially no glass, metals, grit, and noncombustible waste. ### Claim 17 (depends on 16) The engineered fuel feed stock of claim 16, wherein the HHV is between about 5,000 BTU/lb and about 8,000 BTU/lb.
