Production of renewable fuels
The present disclosure relates to methods for the production of transportation fuels from renewable paraffinic feed stocks. The methods disclosed herein present an environmentally-friendly process for using renewable paraffinic feed stocks from various sources. The renewable paraffinic feed stocks can be used to produce a variety of hydrocarbon fuels, including renewable gasoline. The disclosure also relates to fuel products and fuel blend stocks produced from renewable paraffinic feed stocks.
1. A process for producing a renewable hydrocarbon fuel product, the process comprising:
providing a renewable paraffinic feed stock comprising at least 80% C8-C20 hydrocarbons;
reacting said renewable paraffinic feed stock in a fluid catalytic cracking reactor at a temperature ranging from 400° C. to 530° C., and a catalyst to feed stock ratio ranging from 4:1 to 10:1 to produce a renewable hydrocarbon fuel product comprising less than 5% coke;
wherein the renewable paraffinic feed stock comprises 0% to 10% by volume of a petroleum feed; and
wherein said renewable paraffinic feed stock being fed to the fluid catalytic cracking reactor has not been isomerized.
2. The process of claim 1 , further comprising blending said renewable paraffinic feed stock with the petroleum-based feed to produce a renewable paraffinic feed stock blend comprising greater than 0% to 10% by volume of the petroleum feed.
3. The process of claim 1 , further comprising the step of blending said renewable hydrocarbon fuel product with a petroleum fuel product and/or with one or more renewable fuels.
4. The process of claim 1 , further comprising the step of separating said renewable hydrocarbon fuel product into two or more constituent streams.
5. The process of claim 4 , wherein said two or more constituent streams comprise at least two of a fuel gas stream, an ethylene stream, a propylene stream, a butylene stream, an LPG stream, a naphtha stream, an olefin stream, a diesel stream, a gasoline stream, a light cycle oil stream, a jet fuel stream, and a cat unit bottoms (slurry/decant oil) stream.
6. The process of claim 1 , wherein said reacting step is performed in the absence of a sulfur removal pre-treatment step of said renewable paraffinic feed stock.
7. The process of claim 1 , wherein the renewable paraffinic feed stock comprises 0% by volume of the petroleum feed.
8. A process for producing a renewable hydrocarbon fuel product, the process comprising:
providing a renewable paraffinic feed stock;
reacting said renewable paraffinic feed stock in a fluid catalytic cracking reactor at a temperature ranging from 400° C. to 530° C., and a catalyst to feed stock ratio ranging from 4:1 to 10:1 to produce a renewable hydrocarbon fuel product;
wherein the renewable paraffinic feed stock comprises 0% to 10% by volume of a petroleum feed;
wherein said renewable paraffinic feed stock being fed to the fluid catalytic cracking reactor has not been isomerized; and
wherein the reacting step yields less than 5% wt. coke from the cracking of the renewable paraffinic intermediate.
