| Abstract: | This paper studied conditions of hogwash oil hydrolysis technology in acid out,washing,pressure,temperature,hydrolysis and others.This technology took water as the catalyst and could treat complicated catering hogwash oil in a simple way.The technological conditions were： pressure,3.5 Mpa;added water,35%.It should be mentioned that water added was calculated according to neutral oil content,because hydrolysis was not necessary for free fatty acid. |
