| Outline of Final Research Achievements |
Hydrolysis of a cellulose material (filter paper) was carried out in the presence of a metal oxide (heterogeneous) catalyst using a stirred type stainless-steal reactor. The filter paper was decomposed at above 180 °C. The decomposition of the filter paper was accelerated with increasing reaction temperature. Then, the degree of polymerization of the filter paper decreases with increasing reaction temperature, which decomposes to low molecular region (degree of polymerization of about 20) at 240 °C. At 220 °C for 2 hours, the yield of total organic carbon showed the highest. Catalytic reaction using metal oxides was carried out under the condition. As the results, when ZnO and phosphomolybdic acid were used, the hydrolysis proceeded more than in the absence of catalysts, and the product (glucose and oligosaccharide) was larger.
