Abstract
A process for producing olefins from biorenewable feedstocks has been developed. The process comprises first pretreating the feedstock, e.g. vegetable oil, to remove contaminants such as alkali metals and then cracking the purified feedstock in a fluidized catalytic cracking (FCC) zone operated at conditions to provide C2-C5 olefins.
Claims4
A process for the catalytic cracking of biorenewable feedstocks comprising first treating the feedstock in a pretreatment zone at pretreatment conditions to remove at least a portion of contaminants present in the feedstock and produce an effluent stream;
- flowing the effluent from the pretreatment zone to a fluid catalytic cracking zone where the effluent is contacted with a cracking catalyst at cracking conditions to provide a product stream comprising C2-C5 olefins and hydrocarbons wherein the pretreatment step is selected from the group consisting of contacting the feedstock with an acidic ion exchange resin or contacting the feedstock with an acid solution.
