Date Feb. 19, 1981.Process and apparatus for producing furfural from plant materials. The hydrolysis of pentosanes contained in plant materials is effected in a first reactor (2) in the presence of a strong concentrated acid, at 20 DEG -70 DEG C., at atmospheric pressure, and dehydration of the pentoses into furfural is effected in a second reactor (5) by vapor action at atmospheric pressure and at a temperature lower or equal to 110 DEG C., in a strong acid concentrated medium. Application: production of furfural. |
