Abstract: A manufacturing facility of biomass solid fuel includes: a preheater for preheating pellets; a heat source for preheating; a reactor that torrefies the pellets preheated by the preheater; a circulation path that connects a gas outlet and a gas inlet of the reactor and circulates torrefaction gas generated during torrefaction of the pellets in the reactor, a branch flow path branched from the circulation path to flow the torrefaction gas therethrough; a combustor that receives the torrefaction gas flowing through the branch flow path and combusts the torrefaction gas; a first heat exchanger provided in the circulation path; and a first combustion gas flow path connecting the combustor and the first heat exchanger to flow combustion gas generated in the combustor. The first heat exchanger exchanges heat between the combustion gas generated in the combustor and the torrefaction gas circulating in the circulation path.

Abstract: Provided is a lithium hydroxide production method for producing high-purity lithium hydroxide efficiently and at a lower energy, wherein Li ions alone are recovered in a recovery liquid from a lithium ion extract extracted from a processed member of a lithium secondary battery, using a Li permselective membrane, and lithium hydroxide is produced from the recovery liquid.
