| description | A nutrient composition for enhancing biogenic methane production from a carbonaceous material is described. The nutrient composition comprises a source of phosphorus (P) and a source of nitrogen (N), wherein the molar ratio of phosphorus to nitrogen (P/N) is greater than 1.5, and the nitrogen concentration is at least 0.1 m M and less than 1.7 m M. A process for enhancing biogenic methane production from a carbonaceous material is also described. The process involves contacting the nutrient composition of the invention with the carbonaceous material for a period of time to biogenically produce methane and subsequently collecting methane from the carbonaceous material. The process may further comprise contacting the carbonaceous material with a second nutrient composition, wherein the second nutrient composition has a P/N molar ratio greater than the P/N molar ratio of the former nutrient composition.
L'invention concerne une composition de nutriments destinée à améliorer la production biogène de méthane à partir d'une matière carbonée. La composition de nutriments comprend une source de phosphore (P) et une source d'azote (N), le rapport molaire de phosphore à azote (P/N) étant supérieur à 1,5 et la concentration en azote étant d'au moins 0,1 mM et inférieure à 1,7 mM. Un procédé pour améliorer la production biogène de méthane à partir d'une matière carbonée est également décrit. Le procédé implique la mise en contact de la composition de nutriments de l'invention avec la matière carbonée pendant un laps de temps pour produire du méthane par voie biogène et la récupération consécutive du méthane à partir de la matière carbonée. Le procédé peut en outre comprendre la mise en contact de la matière carbonée avec une deuxième composition de nutriments, la deuxième composition de nutriments présentant un rapport molaire P/N supérieur au rapport molaire P/N de la première composition de nutriments. |
