Description
The purpose of this research is to produce 20L/h pilot scale plant for converting the glycerin to the lactic acid.Condition of reaction are reaction temperature 310degree, reaction pressure 11Mpa, glycerin concentration 400kg/m3, sodium hydroxide concentration 174kg/m3.As a result of the operation, it was confirmed that the operation control could be stabilized.At observed material balance, the lactic acid yield was 54wt%, the hydrogen gas yield was 1.2wt%, and survival glycerin yield was 10wt%.The by-product yield except for the lactic acid was 35wt%.Also the corrosion test was carried out in order to select the metal quality of the reactor.As the result, the corrosion resistance might be verified on SUS316L and 600 alloys.
