Abstract: The present disclosure relates to processes for producing hydrocarbon fuels from lignocellulosic biomass. A process may include introducing biomass to a pretreatment system, and a first separation system forming a pentose-rich stream and a pentose-lean stream. The pentose-lean stream may be introduced to a hydrolysis system forming a hydrolysate and the hydrolysate introduced to a second separation system forming a hexose-rich stream and a lignin stream. Additionally, at least one of the pentose-rich stream or the hexose-rich stream may be introduced to a bioreactor containing microorganisms configured to produce hydrocarbon fuels. Additionally, the present disclosure also relates to systems for the production of hydrocarbon fuels. A system may include a pretreatment system, a first separation system, a hydrolysis system, a second separation system, and one or more bioreactors. Alternatively a system may include a pretreatment system, a hydrolysis system, a sugar separation system, and one or more bioreactors.
