Developing countries need a continuous supply of cheap energy. and There are environmental concerns, and common fears in the world today that fossil fuels will soon run out, which made the world look for other sources of energy Biofuels (such as biodiesel) have attracted increasing attention worldwide as a blending component or direct replacement. The main objectives of the research is to produce biodiesel from cooking waste oil using an esterification reaction with a base catalyst was investigated. reactions with molar ratios of oil/methanol from 1:4 to 1:6 using 1 wt% KOH as a catalyst showed an increase in biodiesel yield from 80.236% to 84.916% at 70 ˚C after a curing reaction time of 60 min.; Therefore, the highest yield of 86.245% was achieved at 80 ˚C. We designed a device for the production of biodiesel and compared the best conditions with the device for which it was designed, so the productivity of the device designed under these conditions was 86.842%. In this project, the physical properties of biodiesel for all samples: such as viscosity and its values ranged between [3.223 – 5.129 mpa.s], the kinematic viscosity and its values ranged between [3.815 – 5.977 mm2/s], the flash point whos values the temperatures ranged between [165 – 170 ˚C], the pH whose values ranged between [6.67 –7.94], the density and its values ranged between [840– 880 Kg/m3] and also the moistures content and its values ranged between [936 –1976 ppm]. were studied as part of this research work.
