The waste edible oil fluid catalytic cracking process (FCC), an environment friendly process to produce clean fuel (such as gasoline, diesel) and high-value chemical materials (such as propylene), was studied in an small hot model of downer reactor under the temperature 500 ℃, the pressure 1.1×105Pa , the resident time 1 second, the ratio of catalyst to oil 12 , and MA-83 as the catalyst. Compared with other processes, the waste edible oil FCC process can realize the waster utilizing and adjust the product distribution according to the market demand, while with a convenient pretreatment to the raw materials. The experimental results showed that the waste edible oil and cottonseed oil fluid catalytic cracking process have the similar product distribution: liquefied petroleum gas (LPG) 10.3wt%, gasoline 36.4wt%, diesel oil wt23%. And the desired product the gasoline and diesel with trace content of sulfur, nitrogen and heavy metals, have the similar molecular weight and chemical structure to the gasoline and diesel from petroleum-based fuel. Therefore, the waste edible oil fluid catalytic cracking is a promising process, with both economic and environmental benefit.
