NUTRIENT COMBINATION, PROCESS AND SYSTEM FOR ENHANCING BIOGENIC METHANE PRODUCTION FROM A CARBONACEOUS MATERIAL

摘要

A nutrient combination for enhancing biogenic methane production from a carbonaceous material is described. The nutrient combination comprises a source of phosphorus (P) and gaseous nitrogen (N2). The nutrient combination is preferably substantially fee of gaseous oxygen and/or gaseous NOx and/or SOx. In various embodiments the nutrient combination may comprise a two-phase mixture of a solutionof the soluble source of phosphorus (P) and gaseous nitrogen (N2). A process for enhancing biogenic methane production from a carbonaceous material is also described. The process involves dispersing the nutrient combination of the invention throughout the carbonaceous material for a period of time to biogenically produce methane and subsequently collecting methane from the carbonaceous material.
