Abstract: An apparatus is provided. The apparatus may include an elongated shaft including a passage terminating at a nozzle including a dispersion plate and tapered sidewalls between the dispersion plate and the elongated shaft. The tapered side walls may define a single opening, an outer surface of the sidewalls may define a tapered exit for the opening, an inner surface of the sidewalls may define a non-tapered entrance into the opening, the nozzle is sized to be received by a transmission case inlet, and an internal diameter of the passage is less than the tapered exit.

Abstract: The present invention relates to a method for producing a hydrolysate of from lignocellulose-containing material, comprising pre-treatment with low temperature, hydrolysis and fermentation, wherein hydrolysis is performed by contacting the lignocellulose-containing material with an enzyme composition comprising at least 10% xylanase enzyme protein w/w%.

Abstract: The invention relates to a biomass process comprising split dosage of the cellulose hydrolysing enzyme.
