Abstract
The present application provides a one-step refining process of a hydrocarbon feedstock, said process comprising heating said hydrocarbon feedstock with one or more fatty acids or mixtures thereof, at a temperature below 350° C., to obtain a light hydrocarbon product, wherein said light hydrocarbon product obtained in said process contains no heavy hydrocarbons products.
Claims17
A one-step combined process for preparing a light hydrocarbon product from a non-fractionated or fractionated hydrocarbon feedstock, wherein said process combines refining, isomerisation and cracking of said non-fractionated or fractionated hydrocarbon feedstock in one step,
- characterised in that:
- (a) said one step comprises heating said hydrocarbon feedstock in a reaction vessel with a reactant-catalyst at a vapour temperature below 360° C. to obtain said light hydrocarbon product,
- (b) said light hydrocarbon product is obtained in said process with a total yield of at least 60% and contains no heavy hydrocarbon products,
- (c) said process is accompanied by formation of aromatic hydrocarbons,
- (d) said reactant-catalyst is either a liquid mixture of stearic acid dissolved in ether-aldehyde fraction of ethanol and mixed with technical grade oleic acid, or a solid residue which remains in the reaction vessel after completion of said process, said solid residue activated with the ether-aldehyde fraction of ethanol, wherein said ether-aldehyde fraction of ethanol contains 94-98% of ethanol and 2-6% of ethers, aldehydes, acetone, diacetyl, methanol, nitrates and sulphates.
