METHOD FOR HEATING A FEEDSTOCK |
摘要 |
The present invention provides a method for producing a pretreated or hydrolyzed lignocellulosic feedstock. The method comprises feeding a lignocellulosic feedstock to a plug formation device and forming a feedstock plug therein. The plug or segments thereof are fed into an elongate chamber that comprises steam addition means for direct steam addition and a rotating shaft mounted co-axially within the chamber having one or more disintegrating elements mounted on it. Disintegrated feedstock particles are produced in the elongate chamber by the disintegrating elements. The disintegrated feedstock particles are heated by contact with the steam introduced through the steam addition means. The disintegrated feedstock particles are then treated in a reactor to produce the pretreated or hydrolyzed lignocellulosic feedstock. Further provided is a feedstock composition comprising disintegrated feedstock particles. Also provided are methods for reducing erosion on equipment by maintaining the discharge consistency from the plug formation device below 35 wt %. |
