Abstract

The present disclosure relates to processes for desulfurizing hydrocarbon feedstocks. The processes may include introducing a feedstock comprising hydrogen sulfide to an absorber comprising a metal chelate to form a reduced metal chelate. The processes may further include introducing the reduced metal chelate to a photobioreactor comprising a phototrophic bacterium. The present disclosure also relates to apparatuses for desulfurizing hydrocarbon feedstock. An apparatus may include and absorber and a photobioreactor fluidly connected to the absorber. The photobioreactor may be an anaerobic vessel with a light source.
