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

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.

Experimental design, materials and methods

Materials

Experiments were carried out with bio-oil produced by Botton et al. [2] from thermal cracking of methyl ester in castor oil at 475–525 °C with residence time of 44–104 s.

Distillation curve

Experiments were performed in an automatic vacuum distiller as illustrated in Fig. 1 (B/R Instrument, model M690) [3], [4], based on the standards for petroleum characterization [5], [6]. The data obtained in this analysis is show in Table 1.

GC-FID analyses

All these analyses were performed in triplicate (Table 2). The desired compounds - heptaldehyde and methyl undecenoate - were analyzed by GC-FID using an Agilent GC-FID, model 7890B (Agilent Technologies, Inc., Wilmington, EUA) (Fig. 2, Fig. 3 and Table 3). The carbon number of bio-oil samples were analyzed using a Shimadzu GC-FID, according to Beims et al. [3] by n-alkane comparison (Fig. 4 and Table 4).
