Title: Configurations for a forest refinery: an interim report. [Steam explosion vs acid hydrolysis pretreatment; organosolv vs kraft pulping processes]

Abstract

This report represents a preliminary assessment of a variety of processes capable of manufacturing chemicals from trees. The objective is to screen promising biomass conversion processes in order to set the stage for a subsequent study of the feasibility of integrating the most promising into a single complex. The criteria employed in evaluating potential biomass-based routes vis a vis conventional routes to the same end-products are profit potential and non-renewable energy displacement potential. As is to be expected, the biomass refinery rates quite favorably in the latter category by virtue of using a non-petroleum feedstock. Broad conclusions in the other category are not derived quite so readily. Two pretreatment alternatives have been examined: steam explosion and dilute acid prehydrolysis. The latter option maximizes use of the hemicellulosic wood fraction, while the former would be a necessary step for subsequent enzyme hydrolysis in order to obtain high hydrolysis yields. As there is no conventional alternative process, a comparison of commercial feasibility is not provided. For reference, the analysis shows that steam exploded wood can be produced at a net cost of production (including 15 percent DCF return) of 4.0 cents per pound. Based on this value, the net cost of productionmore » of the dry products from prehydrolysis is 7.1 cents per pound. In order to separate the lignin from cellulose, two pulping alternative have been examined: organosolv and kraft pulping. A chief value of organosolv is that a chemical grade pulp is produced, whereas kraft pulp may not be suitable for chemicals production without further purification. However, the kraft process turns out to be the more economic alternative.« less
