Abstract

The effect of the catalyst V/zeolite KN‑30 on the formic acid yield in the process of oxidative hydrolysis of dissolved hemicellulose oligosaccharides obtained by hydrothermal treatment of aspen wood at 180 °C was established. The catalyst obtained by impregnation of ZSM‑type zeolite KN‑30 with NaVO3 was characterized using the methods of SEM, XRD, BET and temperature ‑programmed desorption of ammonia. Under optimal conditions of the process of oxidative hydrolysis of hemicellulose oligosaccharides (150 ⁰C, air pressure 3MPa, time 3 h) the yield of formic acid was 43 mas.% (in non‑ catalytic process 1.5 mas.%). The catalyst activity in the process of oxidative hydrolysis of oligosaccharides at 150 °C change little over 5 catalytic cycles and formic acid yield was decreased by 7 mas.% after 20 hours of operation
