Effective Gasoline Production Strategies by Catalytic Cracking of Rapeseed Vegetable Oil in Refinery Conditions

Abstract

The incorporation of nickel onto a commercial FCC catalyst and co‐feeding H2 into the reaction system improves the catalytic performance of rapeseed oil cracking, with respect to gasoline and light olefins (propene and butenes) production. On the other hand, the incorporation of platinum, with or without co‐feeding of H2, is detrimental to both the conversion and the selectivity. Thus, a judicious choice of metal is vital for performance during vegetable oil cracking.

Catalytic cracking of carinata oil for hydrocarbon biofuel over fresh and regenerated Zn/Na-ZSM-5

“…Bio-oil can be produced by the pyrolysis of vegetable oil, but it has a high content of oxygenates such as acids, ketones, alcohols and aldehydes [6]. Green diesel can be produced by the hydrotreatment of vegetable oil [8], but H 2 feeding increases the processing cost [2,9]. However, catalytic cracking is an effective and simple method to produce biofuel from vegetable oil, with advantages of low operational cost, flexibility with respect to oil sources, and compatibility with available infrastructures [10][11][12].…”

Optimization of catalytic cracking process for upgrading camelina oil to hydrocarbon biofuel

“…Triglycerides in vegetable oil are cracked into fatty acids through a decomposition. Then, fatty acids are converted into products such as gasoline, heavy hydrocarbons and light gaseous hydrocarbons (Rao et al, 2010). Catalysts with long lifetime and excellent selectivity can reduce the processing cost and improve the product yield.…”

Catalytic cracking of inedible camelina oils to hydrocarbon fuels over bifunctional Zn/ZSM-5 catalysts

“…The long-chain fatty acids would be cracked into short-chain fatty acids, esters, and hydrocarbons. After that, the obtained products would be converted into heavy hydrocarbons, gasoline or light gaseous hydrocarbons [3].…”
