Biodiesel production from tannery fleshings: Feedstock pretreatment and process modeling

Popis výsledku v původním jazyce

During raw hide processing, tanning industries generate large quantities of wastes containing a considerable amount of fat which can be converted into biodiesel. A typical representative of such wastes is fleshings - which however, usually contains a significant amount of free fatty acids, proteins and other impurities. Pretreatment was suggested as a means of processing this acidic feedstock, thereby enabling the reduction of the free fatty acid content under the limit value of 0.5% w/w when the alkalicatalyst is then appropriate for transesterification. The feedstock pretreatment process involved the refining melting of fresh pigskin fleshings with subsequent extraction using a methanol or methanol solution with an equimolar amount of alkali i.e. tetramethylammonium hydroxide, isopropylamine and cyclohexylamine. A mathematical model of the pretreatment process was proposed, verified and used in further simulation calculations - which confirmed that deacidification employing methanol
