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.

Experimental data of the distillation of bio-oil from thermal cracking of methyl ester in castor oil

et al. 2019

This article presents the experimental data on distillation of bio-oil obtained from thermal cracking of a mixture of castor oil and its methyl esters. The interpretation of the data can be found in Menshhein et al. (2019) available on https://doi.org/10.1016/j.renene.2019.04.136. Experiments were carried out using a simple distillation apparatus and the products were quantified and qualified from Gas Chromatography – Flame Ionization Detector (GC-FID) with standards compounds. Data were presented in terms of distillation equipment and distillation curve values of volume and temperature of the crude bio-oil sample. Information about GC-FID methods and chromatograms of from standard heptaldehyde and methyl undecenoate and their analytical curve. Carbon number data of crude bio-oil sample was also showed.

“…Oil type plays an important role in bio-oil characteristics, as demonstrated by Buzetzki et al (2011). Therefore, studies can be found with several different vegetable oil sources, such as palm oil (Mancio et al, 2016), waste fish oil (Wiggers et al, 2009a), soybean oil (Wiggers et al, 2009b), waste cooking oil (Junming et al, 2011;Meier et al, 2015;Periyasamy, 2015), hydrogenated fat (Beims et al, 2018a;Beims et al, 2018b) and rubber seed oil (Lu et al, 2014). In addition, some studies have investigated the conversion of isolated free fatty acids, aiming to increase liquid product yields (Asomaning et al, 2012;.…”

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.
