<p>24 ABSTRACF MFFHOD AND APPARATUS FOR PRFPARING FATIY ACID ALKYL ESTER USING FATFY ACID A METHOD AND AN APPARATUS FOR PREPARING FATTY ACID ALKYL ESTER FOR BIO-DIESELS ARE 5 DISCLOSED, WHEREIN FATTY ACID, SPECIFICALLY FATTY ACID DISTILLATE REACTS WITH ALCOHOL, WITHOUT A CATALYST. THE METHOD DOES NOT REQUIRE THE PURIFICATION PROCESS OF THE CATALYST AND GLYCERIN, AND HAS THE SUPERIOR CONVERSION RATIO OF FATTY ACID. THE METHOD FOR PREPARING FATTY ACID ALKYL ESTER FOR BIO-DIESEL FUELS COMPRISES THE STEP OF ESTERIFYING FATTY ACID RAW MATERIAL WITH ALCOHOL, UNDER A TEMPERATURE OF 200 TO 35011C AND A PRESSURE OF 10 ATMOSPHERIC PRESSURE TO 1 0 BAR. THE APPARATUS FOR PREPARING FATTY ACID ALKYL ESTER FOR BIO-DIESEL FUELS. COMPRISES: THE FIRST REACTOR FOR ESTERIFYING FATTY ACID RAW MATERIA(WITH ALCOHOL UNDER A TEMPERATURE OF 2001C TO 3501C AND A PRESSURE OF ATMOSPHERIC PRESSURE TO 1 0 BAR AND FOR CONVERTING 80 TO 90OF TOTAL FATTY ACID INTO FATTY ACID ALKYL ESTER; AND THE SECOND REACTOR FOR CONVERTING REMAINING FATTY ACID UNCONVERTED AT THE 1-5 FIRST REACTOR INTO FATTY ACID ALKYL ESTER.</p> |
