When ethyl alcohol is manufactured from wood hydrolysed by dilute acid, the most expensive part is heat, which necessitates to use heat efficiently. The author passed the flashed wood hydrolysate from the percolator, before neutrailizing through a mixed layer of lignin and starch materials and got transparent over 10% sugar solution. On this operation., the proportion of lignin and starch materials varies with the size of particles. For example, in the case of fresh starch refuse, that proportion is 1.7 : 1 as the dry matter. The sugar solution obtained by this method is transparent and the yeast can be reused and acclimatized, so that it seems to be able to raise alcohol yield.
