(EN) RAW OIL OR FAT FOR PRODUCTION OF HIGHER FATTY ACID ALKYL ESTER, AND PROCESS FOR PRODUCTION OF HIGHER FATTY ACID ALKYL ESTER

Abstract
(EN)
Disclosed is a process for producing a higher fatty acid alkyl ester by carrying out the transesterification of a glyceride of an oil or fat with a monovalent lower aliphatic alcohol for the purpose of producing a light oil alternative fuel that can be used as a fuel for a diesel engine or the like, wherein particularly a free fatty acid contained in the oil or fat can be removed effectively. The process is characterized in that, prior to the transesterification reaction of a raw oil or fat, the raw oil or fat is treated with a monovalent lower aliphatic alcohol using an alkali metal hydrogen sulfate as a catalyst to esterify a free fatty acid contained in the raw oil or fat and subsequently the raw oil or fat is subjected to the transesterification reaction.

L'invention porte sur un procédé de fabrication d'un ester alkylique d'acide gras supérieur par la conduite de la transestérification d'un glycéride d'une huile ou graisse avec un alcool aliphatique inférieur monovalent dans le but de produire un carburant alternatif au pétrole léger qui peut être utilisé comme carburant pour un moteur diesel ou similaire, procédé suivant lequel en particulier un acide gras libre contenu dans l'huile ou la graisse peut être éliminé de façon efficace. Le procédé est caractérisé par le fait qu'avant la réaction de transestérification d'une huile ou graisse brute, l'huile ou graisse brute est traitée par un alcool aliphatique inférieur monovalent à l'aide d'un hydrogénosulfate de métal alcalin comme catalyseur pour estérifier un acide gras libre contenu dans l'huile ou graisse brute et par la suite l'huile ou graisse brute est soumise à la réaction de transestérification.

 ディーゼルエンジン等の燃料となり得る軽油代替燃料を得るため、油脂のグリセリドを一価の低級脂肪族アルコールでエステル交換し、高級脂肪酸アルキルエステルを得る方法において、特に油脂中に含まれるフリーの脂肪酸を効果的に除去することを目的とする。 原料油脂をエステル交換反応に供するに先立って、まず硫酸水素アルカリ金属を触媒とし、一価の低級脂肪族アルコールで処理し、フリーの脂肪酸をエステル化した後、エステル交換反応に供することを特徴とする。
