Anotācija In the near future foliage wood may be as a real alternative to oil as raw material for production of chemicals and motor fuel. A new approach to solve this problem consisting of differential catalysis of hydrolysis and dehydration reactions has been found. The aimed change of the mechanism of the process has permitted to solve two problems simultaneously: to make increase the furfural yield from 55% up to 75% from theoretical and to diminish 5 times degree of the cellulose destruction. On the basis of theoretical studies a new technology including two-step hydrolysis of foliage wood and other pentosan containing raw material has been elaborated. Since 1997 for the first time in the world's industrial practice this technology yielding furfural and fermentable sugars further processed into bioethanol has been realized in Russia with capacity 4.300 t/a of furfural and 8.800 t/a of bioethanol. The degree of raw material utilization has grown 3 times, the total yield of furfural and fermentable sugars - 4 times when compared to the only furfural production.
