    Abstract: A method for producing a fuel or fuel additive comprising providing a reaction mixture comprising oil and an alcohol in an oil-in-alcohol emulsion and a catalyst for converting the oil to the fuel or the fuel additive. The oil and the alcohol are reacted in the presence of the catalyst, at a concentration below that used in a conventional batch process, to produce the fuel or fuel additive. This low level of catalyst reduces the formation of diols and oxidation products that can diminish the quality of the fuel or fuel additive. The fuel or fuel additive produced is continuously removed during the reaction, effectively de-coupling the concentration of catalyst used from the rate of the two phase reaction.

    Abstract: A rotating process chamber assembly for processing various fluids comprises a substantially cylindrical process chamber has an outer wall extending between two end walls and a substantially cylindrical inner wall spaced radially inward from the outer wall in an axial direction. The outer wall and the inner wall define an annular reaction space therebetween. The housing has a central axis. The process chamber has an inlet located substantially coaxial with the central axial. The process chamber has an outlet located substantially axial with the central axis. A drive is coupled to the process chamber to rotate the housing about the central axis. A plurality of feed channels fluidically couples the inlet and the annular reaction space. A first plurality of product channels fluidically couples the annular reaction space to the outlet.
