    Abstract: The present disclosure pertains to biomass pyrolysis processes and systems that decrease entrainment of char and other contaminants in the pyrolysis vapors by filtering the vapors in a heated container comprising a moving bed granular filter (MBGF), which in turn, comprises granular heat carrier. The granular heat carrier is heated within the MBGF and fed directly to the pyrolysis reactor, optionally along with filtered solids such as char. In certain embodiments, the MBGF additionally comprises at least one upgrading catalyst that contacts the vapors to produce a hydrocarbon mixture fungible with a petroleum-derived transportation fuel, a hydrocarbon transportation fuel component, or mixtures thereof.

    Abstract: The present disclosure relates generally to a two-stage biomass pyrolysis processes that maximize pyrolysis vapor yield from a lignocellulosic biomass while being conducive to commercial-scale throughput of biomass. A lignocellulosic feedstock is first pyrolyzed in a reactor first stage comprising at least one auger at a temperature and residence time that produces pyrolysis vapors derived predominantly from cellulose and hemi-cellulose fractions of the feedstock. Partially-pyrolyzed feedstock from the reactor first stage is then pyrolyzed in a reactor second stage at a higher temperature for an additional residence time to produce additional pyrolysis vapors that are predominantly derived from lignin. Certain embodiments arrange multiple reactor first stages around a single reactor second stage.

    Abstract: The present invention relates generally to the thermal conversion of biomass. Processes are disclosed for converting algal biomass to condensable vapor intermediates such as pyrolysis oil by means of pyrolysis in a reactor comprising at least one auger. The intermediates may be further processed for production of renewable hydrocarbon fuels. The disclosed processes assist in preventing premature devolatization of algal biomass during pyrolysis, thereby increasing efficiency and commercial feasibility.
