Quality of biodiesel produced with soybean grains stored with low temperature
This study evaluated the physical-chemical quality of soybean oil biodiesel as a function of the storage environment of the grains. The experiment was carried out in a completely randomized design, considering two storage conditions, the first in ambient conditions, and the second at a temperature o...
