ResumoAmong the biofuels, bio-oil and biodiesel stand out as more sustainable alternatives to fossil fuels, and non-edible oils are an interesting alternative feedstock as there is no competition with human food. This study aimed to obtain and evaluate the physicochemical properties of bio-oils and biodiesels obtained from crambe oil (Crambe abyssinica), which is not used in human food due to the large amount of erucic acid, which has considerable toxicity. Bio-oils were obtained by thermal cracking of the oil without catalyst at three different temperatures, 400, 600, and 800 °C, and methyl and ethyl biodiesel were obtained through alkaline transesterification reaction. The chemical components of the bio-oils were determined by gas chromatography and showed the presence of hydrocarbons, alcohols, ethers, and ketones, and the absence of aromatic compounds. The physico-chemical properties were evaluated, and all bio-oils and biodiesels presented values within the required range for commercialization as biofuels, except for the acidity index. Esterification of the bio-oils improved the acidity index, and moisture helped to improve the physico-chemical properties of the bio-oil, and as CCS600 presented the highest amount of hydrocarbons, it was the most suitable for use as bio-oil.
