3D printed micro-chemical plant for biodiesel synthesis in millireactors

Continuous acid-catalyzed esterification using a 3D printed rotor–stator hydrodynamic cavitation reactor reduces free fatty acid content in mixed crude palm oil

“…Ethanol and sunflower oil were pumped at 140 and 160 mL/min, respectively. The biodiesel yield from the micro-chemical plants was determined using four millireactors, where yields of 51.2 vol%, 43.2 vol%, 31.3 vol%, and 52.3 vol% were achieved for reactor units 1, 2, 3, and 4, respectively [41] . A preliminary study was conducted to test the ABS filament corrosion by monitoring changes in the rotor weight and by visually analyzing the rotor surface.…”

How chemical engineers can contribute to fight the COVID-19

“…The 3D printing can be employed to fabricate a chemical microplant for biodiesel synthesis, including microreactors, flow distributors and mechanical supports [ 49 , 50 , 51 ]. In the separation engineering, 3D printers were used to manufacture distillation and absorption columns, including the development of trays and packs aiming higher specific area internals to enhance the separation [ 52 , 53 ].…”

Evaluation of Reaction Between 2,4-Thiazolidinedione and P-Methoxybenzaldehyde in Microreactors for Production of Drugs for Treatment of Diabetes Mellitus Type 2

“…The increment of production rate is simpler, usually carried out by scaling-up the reactor volume that is an issue in conventional scales due to the difficulty to keep efficient heat transfer and agitation. The increment on production rate of MRs can be accomplished by the parallelization of microdevice units (numbering-up) keeping the transport phenomena characteristics of the individual MR [4,5].…”
