Abstract
Process for manufacturing a hydrogen-containing synthesis gas from a natural gas feedstock, comprising the conversion of said natural gas into a raw product gas and purification of said product gas, the process having a heat input provided by combustion of a fuel; said process comprises a step of conversion of a carbonaceous feedstock, and at least a portion of said fuel is a gaseous fuel obtained by said step of conversion of said carbonaceous feedstock.
Claims21
A process for manufacturing a hydrogen-containing synthesis gas from a natural gas feedstock, comprising the conversion of said natural gas into a raw product gas and purification of said raw product gas, the process having a heat input provided by combustion of a fuel,
- wherein said process comprises a step of conversion of a carbonaceous feedstock and at least a portion of said fuel is a gaseous fuel obtained by said step of conversion of said carbonaceous feedstock,
- wherein said carbonaceous feedstock is solid or liquid and said step of conversion of said carbonaceous feedstock into gaseous fuel is carried out with a gasification process in a gasifier, said conversion of natural gas into said raw product gas includes a reforming step in a reforming section,
- the effluent of said gasifier is used as fuel, not as reforming feedstock, and provides at least part of the total amount of fuel directed to said reforming section.
