Catalytic conversion of vegetable oils in a continuous FCC pilot plant

FCC coprocessing oil sands heavy gas oil and canola oil. 1. Yield structure

“…They reported that the aromatics content in the liquid effluent increased with higher addition of biomass in the blend. In a similar study, Bielanshy et al [10] postulated that coke was formed through polymerization of aromatic hydrocarbons in the cracked liquid product together with the condensation reaction involving the vegetable oil.…”

“…The catalyst used was an industrial FCC equilibrium catalyst. Bielansky et al [9,10] investigated FCC performances of admixtures of rapeseed, soybean, and palm oil, each added in steps of 20 wt% (up to 100 wt%) to a conventional VGO. Cracking took place in a continuous FCC pilot plant with internal circulating fluidized bed (CFB) design using a commercial FCC equilibrium catalyst, an acidic spray-dried rare earth-exchanged USY catalyst partially coated with ZSM-5 zeolite crystal.…”

Fluid catalytic cracking: Processing opportunities for Fischer–Tropsch waxes and vegetable oils to produce transportation fuels and light olefins

“…8) shows that the saturated fatty acid results in much lower aromatics compared to unsaturated fatty acids. A recent study by Bielansky et al [38] also reported that the total amount of aromatics in the liquid fraction (gasoline + LCO) is highest for the more unsaturated vegetable oil. The trend for the aromatic content follows the order: palm oil < rapeseed oil < soybean oil.…”

“…In order to evaluate the potential of vegetable oils as feedstocks in actual FCC process, it is very important to carry out catalytic cracking of vegetable oils under realistic FCC conditions. Not many studies are available on catalytic cracking of vegetable oils in a riser-type reactor [31][32][33][34][35][36][37][38][39].…”

Olefins from Biomass Intermediates: A Review

“…Neste Oil is also using the NExBTL (Next Generation Biomass to Liquid) process in order to produce liquid fuels and olefins [96]. Through steam cracking and fluid catalytic cracking, liquid fuels and C3H6 can be formed, while via the first route olefins are primarily produced [97]. The first step of the steam cracking process is hydro deoxygenation of fatty acids and triglycerides, resulting in green hydrocarbons and naphtha.…”
