“…Moreover, it was observed that in the cracking reaction in this work, when compared with data found in the literature, at relation to mass yield in gasoline fraction, this is was very low, confirming the specificity of sodium carbonate to form hydrocarbons of long-chain. For example in Twaiq (2004) [14], which obtained a yield of 38 to 47% at gasoline fraction using ZSM-5 as catalyst, while in the present study it was obtained only 10% of green gasoline.…”

“…Dandik and Aksoy (1998) [13] measured the conversion of residual sunflower oil by cracking with temperatures between 400 and 420ºC, using as catalysts, the sodium carbonate, aluminium silicate and HZSM-5, with the obtaining maximum percentage of liquid hydrocarbons about 32.8%, being confirmed the presence of hydrocarbons on the range of gasoline. Twaiq et al (2004) [14], studied the performance of materials containing ZSM-5 on the palm oil cracking, being those performances compared to HZSM-5 and MCM-41 catalysts, obtaining as result a conversion of the palm oil equal to 80% and a gasoline fraction yield of 38 to 47%.…”

“…In subsequent work, the same group used HZSM-5 crystals to coat aluminosilicate mesoporous material. The composite materials gave similar palm oil conversion compared to HZSM-5, but lower yields of gaseous products, higher yields of liquid products, and decreased aromatic content in the gasoline fraction [10].…”

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.

“…In addition, the pyrolysis process is very fast, making it more efficient in term of time, and does not require expensive equipment. With the above advantages, pyrolysis technique has been applied to produce liquid fuels from various raw materials, such as coconut oil and palm oil 10,11 , kranji seeds 12 , used tires 13 , and palm oil empty bunches 14 . In practice, pyrolysis is more widely carried out in the presence of catalyst, since this agent has been acknowledged to function not only to accelerate the process but also to determine the type of compound (component) in liquid fuel produced.…”

In this investigation, co-pyrolysis of sugarcane bagasse and sludge palm oil for production of liquid fuel was investigated. A series of pyrolysis experiments was conducted using zeolite-Y synthesized from rice husk silica and aluminum metal through sol-gel route and calcined at different temperatures as catalyst. The pyrolysis experiments were conducted at fixed temperature of 350 o C, and the liquid fuels produced were analyzed using gas chromatography-mass spectrometry (GC-MS) technique for component identification. The results obtained indicate that the main component of the liquid fuels is hydrocarbon, with the highest content of 80% was produced with the use of catalyst calcined at 700 o C. Production of liquid fuels with high hydrocarbon content and practically contain no acids demonstrated that catalyst zeolite-Y synthesized exhibited appreciable selectivity toward formation of hydrocarbons, and simultaneously prevent the formation of acids.
