BIODIESEL PRODUCTION PROCESS WITHOUT CATALYST IN CONTINUOUS CONDITIONS

摘要

This is a non-catalytic continuous process to produce biodiesel from vegetable oil, and ethanol or methanol.It consists of pumping a mixture of vegetable alcohol (13) through a pump (01) to a tubular reactor (02) where it will be submitted to high temperature and pressure, obtaining non-reactive alcohol (12) (ethanol or methanol) at the exit, glycerin (11), and a mixture of esters (biodiesel (10)) which is conducted to the exit reservoir of the reactor (08) where there is an upper alcohol (12) phase (04) that is redirected to the pump's entry (01) via a alcohol (15) return tubing, and the intermediate biodiesel (10) phase (05) and the lower phase (06) (greatest part of glycerin) (11) are directed to the separation reservoir or decantation tank (09) where the final separation is done, wherein the alcohol (12) is separated and then withdrawn through the alcohol (15) return tubing, and having the biodiesel (10) and the glycerin (11) as final products, which are then collected for their final purpose.
