Biodiesel production through non-conventional supercritical routes: Process simulation and technical evaluation

•Three non-conventional supercritical biodiesel production processes are simulated.•Triacetin and glycerol dicarbonate are produced as by-products instead of glycerol.•Route 1 proved feasible in every scenario and is the less energy intensive route.•Route 2 demands 3–4 times more energy and was not...
