This paper presents the new results of energy plant –
rye and triticale at yellow ripeness and ripe, pretreatment in high
pressure steam reactor and monosaccharide extraction. There were
investigated the influence of steam pressure (20 to 22 bar), retention
duration (180 to 240 s) and catalytic sulphuric acid concentration
strength (0 to 0.5 ) on the pretreatment process, contents of
monosaccharides (glucose, arabinose, xylose, mannose) and
undesirable bycompounds (furfural and HMF) in the reactor. The
study has determined that the largest amount of monosaccharides
(37.2 of glucose, 2.7 of arabinose, 8.4 of xylose, and 1.3
of mannose) was received in the rye at ripe, the samples of which
were mixed with 0.5 concentration of catalytic sulphuric acid, and
hydrolysed in the reactor, where the pressure was 20 bar, whereas the
reaction time – 240 s.
