“…The results were verified with Minitab statistical software (State College, PA, USA) for constant variance, independent errors, randomization, zero mean, and contained no outliers. The reaction temperature range (410-430 °C) was based on a preliminary study performed by Luo and co-workers [19], which accounts for the narrow range employed. Reaction time was based on previous studies, conducted by (1) Kubatova et al [18] and (2) Chew and Bhatia [20], in similar reaction systems.…”

While HZSM-5 catalytic cracking of crop oil toward aromatics have been well documented, this work adds to this body of knowledge with a full acid byproduct analysis that provides improved mass balance closure along with a design of experiment optimization of reaction conditions. Fatty acids are an inevitable byproduct when converting any triglyceride oil, but are most often overlooked; despite the impact fatty acids have on downstream processing. Acid analysis verified that only short chain fatty acids, mainly acetic acid, were present in low quantities when all feed oil was reacted. When relatively high fatty acid amounts were present, these were mainly uncracked C16 and C18 fatty acids. Optimization is a balance of aromatics formation vs. unwanted gas products, coke and residual fatty acids. A design of experiments approach was used to provide insight into where the optimal reaction conditions reside for HZSM-5 facilitated reactions. These conditions can then form the basis for further development into a commercially viable process for the production of renewable aromatics and other byproducts.

“…The product crackate from the non-catalytically cracking of soybean oil yielded 89 wt% condensable liquids and 11 wt% non-condensable gases. Because the focus of the present work was on acetic acid recovery, the organic liquid product distilled from the crackate was lighter in molecular weight and lower in yield than those reported in previous work [5,6]. The organic liquid product (OLP) recovered was 24.5 wt % of the feed crackate.…”

“…Non-catalytic cracking leads to a number of such co-product options, including high purity carbon, aromatics, and short chain fatty acids [5]. Kubatova, et al [6] found that the non-catalytic cracking of canola and soybean oils results in 15 wt%-25 wt% C2-C10 linear saturated monocarboxylic acids.…”

The Production of Vinyl Acetate Monomer as a Co-Product from the Non-Catalytic Cracking of Soybean Oil

Abstract:Valuable chemical by-products can increase the economic viability of renewable transportation fuel facilities while increasing the sustainability of the chemical and associated industries. A study was performed to demonstrate that commercial quality chemical products could be produced using the non-catalytic cracking of crop oils. Using this decomposition technique generates a significant concentration of C2−C10 fatty acids which can be isolated and purified as saleable co-products along with transportation fuels. A process scheme was developed and replicated in the laboratory to demonstrate this capability. Using this scheme, an acetic acid by-product was isolated and purified then reacted with ethylene derived from renewable ethanol to generate a sample of vinyl acetate monomer. This sample was assessed by a major chemical company and found to be of acceptable quality for commercial production of polyvinyl acetate and other products.
