摘要： This invention is directed to a process for treating biomass. The biomass is treated with a biomass swelling agent within the vessel to swell or rupture at least a portion of the biomass. A portion of the swelling agent is removed from a first end of the vessel following the treatment. Then steam is introduced into a second end of the vessel different from the first end to further remove swelling agent from the vessel in such a manner that the swelling agent exits the vessel at a relatively low water content.

摘要： A method of extracting sugar, starch, and/or carbohydrates from feed material such as corn or corn stover is disclosed. The feed material is mixed with liquid and perhaps accelerants to form a mixture. The mixture is pumped through a controlled cavitation reactor, where it is exposed to shockwaves from cavitation events. The shockwaves open pores in the feed material and force liquid in and out of the pores to liberate trapped sugars and starches, which are dissolved in the liquid for subsequent removal.

摘要： The arrangement and method for the steam pre-treatment of chips during the production of cellulose pulp avoids the blow-through of gases in the steam pre-treatment vessel. This prevents foul-smelling gases from being released into the atmosphere. The inlet of the vessel has an inclined feeder device in a feeder-housing. In the event of the initiation of the risk for blow-through of steam, the feeder housing is sprayed with cooling liquid in order to increase condensation capacity of the chips being fed into the vessel. Ultimately the feeder housing is filled with liquid that establishes a liquid lock, and preferably at the same time as the feeder drive (M) is shut off. This avoids the emission of gases from the chip bin when interruptions in the process occur so that the release of odors into the surroundings is minimized.

摘要： Disclosed are a method of hydrolysis of wet fiber and a method for preparing ethanol. Generally, an agricultural plant material, such as corn hulls, distiller's dried grains, or spent germ, is treated to at least partially hydrolyze the fiber. The process may include a maceration step followed by a shearing operation in the presence of steam to yield a treated product, in which, in many embodiments, saccharides will be released and unbound from fibrous portions of the agricultural product. In some embodiments, the process includes macerating the material to provide a slurry having a solids content of at least 10 percent and jet cooking the slurry. A mixture of saccharides prepared in this fashion may be fermented to yield ethanol and/or biochemicals.

摘要： An improved method for treating lignocellulosic material, including a prehydrolysis-mass transfer process, which produces a concentrated hydrolysate volume during the time required for the hydrolysis itself. The improved process comprises the heating of the digester and chip content by direct steam to the required hydrolysis temperature, starting a flow of hot, stored hydrolysate to the top of the chip bed in order to create a trickle-bed type down-flow of hydrolysate, collecting a first fraction of the trickled-down hydrolysate as a product fraction, adding extraction liquid and continuing the trickle flow to collect a second hydrolysate fraction, which will be discharged from the digester to a hot hydrolysate storage tank to be used as the first trickle flow liquid in the next batch.
