NOVELTY - Producing synthesis gas conversion product (801) comprises: reforming a carbonaceous feedstock comprising carbonaceous material to produce a first synthesis gas (800) comprising hydrogen and carbon monoxide; subjecting a portion of the first synthesis gas to catalytic conversion, where a portion of the hydrogen and carbon monoxide is converted into synthesis gas conversion product; separating a byproduct including a tail gas or a spent catalyst product from the synthesis gas conversion product; and utilizing a portion of the byproduct during reforming of additional carbonaceous material.    USE - The method is useful for producing synthesis gas conversion product including liquid hydrocarbons (claimed).    ADVANTAGE - The method provides the producing synthesis gas conversion product by utilizing sustainable and renewable feed stock i.e. biomass, facilitating sequestration of carbon dioxide and/or reducing the amount of waste material produced, thus it is environmentally friendly and economical; and allows the separated spent catalyst/product to be recycled by subjecting to reforming along with carbonaceous feed material to produce additional synthesis gas from the product, thus improving the overall liquid yields of the biorefinery and reducing the disposal of material.    DETAILED DESCRIPTION - Producing synthesis gas conversion product (801), comprises: reforming a carbonaceous feedstock comprising at least one carbonaceous material to produce a first synthesis gas (800) comprising hydrogen and carbon monoxide; subjecting at least a portion of the first synthesis gas to catalytic conversion, where at least a portion of the hydrogen and carbon monoxide is converted into synthesis gas conversion product; separating from the synthesis gas conversion product, at least one byproduct including (a) a tail gas comprising at least one component including carbon monoxide, hydrogen, methane or carbon dioxide, or (b) a spent catalyst product comprising the synthesis gas conversion product and catalyst that has been at least partially deactivated and/or attrited during catalytic conversion; and utilizing at least a portion of the byproduct during reforming of additional carbonaceous material.
