“…Liquid phase analyses were performed following the method developed by Kubatova et al [17,18]. The analyses of nonpolar hydrocarbons were performed using an Agilent 7890 gas chromatograph equipped with an Agilent 7683B series autosampler and two parallel detectors: a flame ionization detector (FID) and a HP-5975C Mass Spectrometer (MS).…”

“…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. The range of catalyst weight employed (19-38 grams) was based on the work of Katikaneni and co-workers [11] and verified in our laboratories in preliminary studies [21].…”

Optimizing the Production of Renewable Aromatics via Crop Oil Catalytic Cracking

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.

“…Various production technologies using such raw materials have been investigated based on reactions such as transesterification 1) 3) , hydrotreating process 4) 6) , thermal cracking 7) , catalytic cracking 8) 12) , depending on the demand for the final product. Transesterification is the most common technique, but requires more processes to purify the organic liquid products, which include not only fatty acid methyl esters but also glycerol and carboxylic acids.…”

Zeolite-containing catalysts with hierarchical structures were prepared by combining microporous zeolites (beta and Y zeolite) with mesoporous matrices (silicas and silica _ aluminas with large mesopores) prepared by the gel skeletal reinforcement method and a binder. Morphology of the prepared catalysts was characterized by X-ray diffraction, nitrogen adsorption-desorption, ammonia adsorption-desorption, and thermogravimetric-differential thermal analysis. Catalytic cracking of soybean oil was performed with these mixed catalysts to observe the effect of the pore size on the catalytic activity and the selectivity of products using the convenient Curie point pyrolyzer. Zeolite-containing mixed catalysts exhibited great improvements in all aspects such as maximum increase of 31 % conversion, about 10 % higher gasoline yields, and maximum decrease of 36 % coke formation in comparison with single zeolite, indicating that the presence of the matrices greatly influenced the catalytic cracking. The yields of gasoline, single branched and multi-branched hydrocarbons increased with higher conversion, indicating that increased conversion was necessary to obtain higher yields of products. In comparison of product yields at the same conversion, Y zeolite-containing catalysts exhibited the higher yields than beta (β) zeolite-containing catalysts, indicating that the larger micropore diameter of Y zeolite in the catalysts induced the increase in the gasoline fraction and promoted the isomerization to produce the bulkier products. The conversion of soybean oil increased with increasing the pore diameter for β series catalysts and the conversions were maximum for MAT (

“…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.…”

“…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. These acids have market values that range from comparable to transportation fuels (C2: acetic acid) to many times the value of fuels (C7-C10).…”

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.
