Bio‐oil produced from triglycerides thermal cracking is a complex mixture of hydrocarbons and oxygenated compounds and is a potentially renewable source for fuel and chemical production. The presence of carboxylic acids results in a high acid index making it difficult to refine and use it as a fossil fuel substitute. This high acidity causes corrosion and may interfere on the final applications. In this work, soybean oil was thermally cracked, and the bio‐oil was characterized and submitted to esterification reactions in order to evaluate the effect of temperature and reactants mass ratio. Before esterification, crude bio‐oil showed 8.61% of carboxylic acids in GC–MS characterization and an acid index of 133.33 mg KOH/g. The reactions were conducted for 90 min, from 50 to 65°C for methanol and from 60 to 75°C for ethanol, and the bio‐oil‐alcohol mass ratio from 10:1 to 1:1. Methylic and ethylic esterification at 1:1 mass ratio of bio oil to alcohol at 65°C and 75°C showed decrease of 97.5 and 90.4% in the acid index, reaching values of 3.35 and 12.65 mg KOH/g, respectively. These results demonstrate the potential of using esterification in bio‐oil to reduce its acidity and improve its quality.

“…Nevertheless, the determination of the physical and chemical properties of bio-oil is usually complex and expensive due to the large number of different compounds, which leads to barriers in the industrial application of thermal cracking (Butler et al, 2011). The determination of bio-oil properties is necessary to provide enough data to propose satisfactory kinetic mechanisms for the thermal cracking reaction, which may provide information on the operating conditions aiming at process development and scaling up studies (Wiggers et al, 2017) as well as investigations on co-processing operations with crude oil in a standard refinery plant (Beims et al, 2017). Hence, constructing the distillation curve could address these issues, since it is a key method for gathering information on complex mixtures such as bio-oil and petroleum.…”

“…The aim of this research was to apply the distillation curve in the characterization of bio-oil, based on a well-known method used in the petroleum industry. This could be an important support tool for bio-oil co-processing (Wiggers et al, 2017;Beims et al, 2017), process simulation and the design and scale-up of operations.…”

Bio-oil obtained from thermal cracking of waste cooking oil (WCO) is a complex mixture of different chemical compounds and, like crude oil, it is composed mainly of hydrocarbons. The large number of compounds in bio-oil leads to complex and expensive methods for its properties determination. In this study, the distillation curves were constructed for samples of bio-oils obtained from the thermal cracking of WCO in order to predict the properties (such as molecular weight, viscosity and refractive index). Although it is not often employed for bio-oil analyses, the distillation curve method is commonly used in the petroleum industry. Atmospheric and vacuum distillations were performed according to ASTM D86 and ASTM D1160 standards, respectively, for six samples of bio-oil and one sample of crude oil. The results were converted to true boiling point (ASTM D2892) according to the API method (1997) and common petroleum refining correlations were employed. The estimated values for the properties showed little deviation in relation to the experimental data. The bio-oil and crude oil samples contained heavy compounds in their composition, and all samples studied are considered as heavy oils considering the °API range.
