Abstract
V novem postopku proizvodnje furfurala segrevamo surovino, ki vsebuje pentosan in je okisana ali ne, do temperature T1, z dovajanjem pare skozi ventil (2), medtem, ko sta ventila (3, 4) zaprta. Po zelo kratkem postopku segrevanja, para kondenzira in tako poveča vsebnost vlage polnila. Nato ventil (2) zapremo in odpremo izpustni ventil (3), da nastane stalen majhen pretok pare produkta s postopnim zmanjševanjem tlaka. To povzroči počasen padec temperature. Ko tako dosežemo primerno določeno temperaturo T2, izpustni ventil (3) zapremo in tako zaključimo prvo postopno zmanjševanje tlaka. Če ob koncu tega ciklusa ne moremo dobiti nič več furfurala, postopek zaključimo tako, da odpremo ventil (4) in iz posode izpraznimo ostanek. Če pa furfural lahko pridobivamo še naprej, reaktor ponovno segrejemo in pričnemo nov ciklus postopnega zmanjševanja tlaka.
Claims (10)
1 PATENTNI ZAHTEVKI 1.
