Document Type and Number:
WIPO Patent Application WO/2020/080609
Kind Code:
A1
Abstract:
A device for producing sludge into a liquid fuel according to the present invention may comprise: a settling tank formed to settle supplied sludge and remove settled inorganic materials from the sludge; an aging tank which is supplied with the sludge, from which the inorganic materials have been removed in the settling tank, and in which the sludge, from which the inorganic materials have been removed, is at least partially aged to be activated; a mixing tank formed to supply water to the sludge at least partially aged in the aging tank; a pump for applying high pressure to the sludge mixed with water in the mixing tank; a subcritical reactor into which the sludge in the subcritical phase is introduced by the pump and which causes a reaction to convert the sludge in the subcritical phase into a mixture phase containing a liquid fuel; and a separator for separating and extracting the liquid fuel from the mixture containing the liquid fuel.
