A process for converting lignocellulosic feedstock includes providing a lignocellulosic feedstock into a first inlet of a first reactor at a first end, and providing a hot feedstock into a second inlet of the first reactor at a second end of the first reactor. The process includes heating and reacting the lignocellulosic feedstock with the hot feedstock and outputting a first product stream from a first product outlet of the first reactor. The first product stream is an alkane rich product stream. A reactor system includes a first reactor having a first inlet at a first end, a second inlet at a second end and at least one product outlet. The first reactor is configured to receive a lignocellulosic feedstock at the first inlet and a hot feedstock at the second inlet. The system includes a second reactor having a first inlet downstream from the at least one product outlet.
