Abstract

Aditivna proizvodnja omogućava izradu modela složenih geometrija s veoma sitnim detaljima. Jedna od najraširenijih tehnologija aditivne proizvodnje je proizvodnja rastaljenim filamentom, FFF. Materijal korišten za izradu cijevnih mikroreaktora ovom metodom je F43 Tough na osnovi poliolefina. Svojstva ovog materijala su dobra kemijske otpornost koja je ispitana testom bubrenja i visoka transparentnost koja omogućava vizualno praćenje reakcija. Cilj ovog rada bio je izraditi cijevne mikroreaktore promjera 100 μm, 200 μm, 300 μm, 500 μm, 800 μm i 1000 μm postupkom proizvodnje rastaljenim filamentom te u njima provesti reakciju sinteze biodizela. Sinteza biodizela provedena je u izrađenim mikroreaktorima promjera mikrokanala 500 μm, 800 μm i 1000 μm, s različitim vremenima zadržavanja. Konverzija je ispitana metodama infracrvene spektroskopije s Fourierovim transformacijama i plinskom kromatografijom. Rezultati obje analize pokazuju isti trend konverzije Dobiveni rezultati pokazali su da je najbolja konverzija u mikroreaktoru promjera mikrokanala od 800 μm s najvećim vremenom zadržavanja od 10 minuta.

Abstract (english)

Additive manufacturing enables the creation of complex geometric models with very small details. One of the most widespread technologies of additive manufacturing is the Fused Filament Fabrication, FFF. The material used to make tubular microreactors using this method is F43 Tough based on polyolefins. The properties of this material are good chemical resistance, tested by swelling test, and high transparency which allows visual monitoring of the reaction. The aim of this study was to make tubular microreactors with diameters of 100 μm, 200 μm, 300 μm, 500 μm, 800 μm and 1000 μm using the process of filament fused fabrication and to carry out biodiesel synthesis reaction within them. The synthesis of biodiesel was carried out in fabricated microreactors with microchannel diameters of 500 μm, 800 μm and 1000 μm with different retention times. The conversion was examined with infrared spectroscopy and gas chromatography. The results of both analyses show the same conversion trend. The results show that ultimately the best conversion results in a microreactor is a microchannel of 800 μm diameter with a maximum retention time of ten minutes.
