Abstract

Both non-catalytic and catalyst-facilitated cracking of unsaturated triacylglycerides (TG) produces an organic liquid product (OLP) that can be further processed into replacements for petroleum derived transportation fuels and petrochemicals. The thermal non-catalytic cracking of jojoba oil, a non-TG based wax produced by the desert plant, Simmondsia chinensis, was studied using a flow reactor and by comparison with a common triacylglycerol based oil, soybean. Optimum organic liquid product (OLP) yield was produced at a higher cracking reaction temperature for jojoba oil compared to soybean oil but at similar reaction pressure. At optimum conditions, jojoba oil generated a similar fraction of noncondensible compounds as soybean oil. Jojoba oil cracking OLP yield declined at a lower residence time, 3 min, and either higher or lower temperatures, producing a large fraction of products. At optimized conditions, ≈ 90% of the OLP could be quantified using GC analysis. Jojoba oil may be a suitable feedstock for the production of renewable replacements for petroleum-derived transportation fuels and chemicals.
