Non-catalytic cracking of jojoba oil to produce fuel and chemical by-products

A review on recent advancement in catalytic materials for biodiesel production

“…Kozliak et al [64] reported that in a bench-scale continuous thermal cracking process of non-triglycerides jojoba wax-oil performed in the presence of nitrogen pressure of 14.8 Â 10 5 Pa, reaction temperature of 450 1C was required for the formation of the desired products. It was reported that jojoba wax-oil remained uncracked at 420 1C, while, the reaction temperature of 470 1C resulted in overcracking which directed the generation of unwanted gas products.…”

“…In addition, the reaction variables heavily decide the selectivity of the products. The presence of glycerol backbone in TAGs molecules directs the formation of intermediates, particularly ketene, ethyl radical, propylene, and ethylene oxides which initiates the polymerization reaction and are also responsible for the gaseous product formation [64,67].…”

The Impact of Fatty Acid Composition on Transportation Fuel Yields via the Non‐Catalytic Cracking of Triacylglyceride Oils

“…It should be noted that most algae-and microbial-derived TG oils have concentrations that primarily fall within the spectrum of concentrations in the study oils [14], so these results should be widely applicable. Other, less commercially available but more unusual oils, such as jojoba oil, have also been studied [15], but are not reported here.…”

“…Instead, this was the final experimental step for the batch reactor samples and this OLP was analyzed in detail in the study and then used in simulation models for the remaining steps in the process. The processing of non-catalytically cracked TG oils at the lab-scale into DCB transportation fuels has been reported previously [14][15][16]23].…”

“…Fuels generated from TG oils have negligible sulfur and metals content, further increasing their value as environmentally friendly alternatives to petroleum-based fuels. While technologies based on hydroprocessing [2] are the first to enter the commercial domain, noncatalytic cracking is considered the most developed TG oil-based technology that produces true DCBs [14][15][16].…”
