| titleOfInvention | continuous process for pretreatment of a lignocellulosic feed load |
| abstract | CONTINUOUS PROCESS FOR PRE-TREATING A LIGNOCELLULOSTIC FEED LOAD. The present invention is directed to a continuous process for pretreatment of a lignocellulosic feedstock. A feed loading suspension is provided which has a solids concentration of 10% to 30% by weight. The feedstock suspension is pumped through a heating train of at least two stages, each stage including a pump to increase stage pressure and a direct steam injection to heat the feedload suspension. Acid is also added to the feedstock suspension prior to the heating train, during a heating stage, or after leaving the heating train; The acid is added at a concentration of 0.2% to 12% by weight of acid based on the weight of the initial feedstock. A heated, acidified feed cargo suspension is thus produced. The heated, acidified feedstock suspension is drained through a pretreatment reactor at a temperature of 160 ° C to 280 ° C for a time sufficient to increase the conversion of cellulose into the glucose feedstock. using cellulase enzymes. After the suspension leaves the pretreatment reactor, it is cooled using two, or more than two, stages of instant vaporization at successively lower pressures without increasing the vapor pressure after instant vaporization. Steam energy at or near the instantaneous vaporization pressure from two or more than two of the instantaneous vaporization stages is used to heat the supply load suspension in the heating train. |
