Methods, processes, systems, or apparatus are provided to remove contaminants such as metals and chlorine present in a pyrolysis stream to form reduced-contaminant liquid biomass. In certain embodiments, for example, a metal chelating agent is dissolved into a metal-containing pyrolysis stream condensate to form metal chelate complex, followed by filtering to obtain the reduced-contaminant liquid biomass.
