Abstract: The invention discloses a method for producing bio-fuel (BF) from a high-viscosity biomass using thermo-chemical conversion of the biomass in a production line (10) with pumping means (PM), heating means (HM) and cooling means (CM). The method has the steps of 1) operating the pumping means, the heating means and the cooling means so that the production line is under supercritical fluid conditions (SCF) to induce biomass conversion in a conversion zone (CZ) within the production line, and 2) operating the pumping means so that at least part of the production line is in an oscillatory flow (OF) mode. The invention is advantageous for providing an improved method for producing biofuel from a high-viscosity biomass. This is performed by an advantageous combination of two operating modes: supercritical fluid (SCF) conditions and oscillatory flow (OF).

Abstract: Embodiments described herein relate to an apparatus for a feeder system. The apparatus includes a reactant source, a reactant reservoir, a frame, and a valve. The reactant source contains a first reactant. The reactant reservoir receives the first reactant from the reactant source and applies a second reactant to the first reactant to facilitate a chemical reaction. The frame is coupled to the reactant source to maintain the reactant source gravitationally directly above the reactant reservoir. The valve is disposed between the reactant source and the reactant reservoir to control flow of the first reactant into the reactant reservoir.

Abstract: A camera system for providing multispectral imaging of an object, the camera system having a longitudinal axis. The camera system comprises a quasi-collimating lens capable of receiving light from the object and separating wavelengths of the light. Each wavelength is projected to one of a plurality of intermediate image locations which are separated along the longitudinal axis. The system also comprises an achromatic imaging lens to receive the projected wavelengths of light from the quasi-collimating lens, and a pixelated detector positioned to receive the light from the achromatic imaging lens. The achromatic imaging lens and the pixelated detector are movable relative to one another in the direction of the longitudinal axis. The system is configured such that the projected wavelengths of light each form a corresponding image, the images formed on the detector when different distances within the range are achieved.
