Abstract

A method for producing green olefins and green gasoline from renewable sources, the method including: providing CO2 and hydrogen as feed to produce methanol in a methanol reactor, to produce an MTO reaction effluent, reacting the MTO reaction effluent in a plurality of separation columns to separate hydrocarbons, wherein the plurality of separation columns includes a Deethanizer column, a Depropanizer column, and a Debutanizer column, hydrogenating a fraction of separated hydrocarbons in the Debutanizer column with the hydrogen in a hydrogenation reactor, wherein the fraction of separated hydrocarbons from the Debutanizer column includes C5+ hydrocarbons; producing the green gasoline and Liquefied Petroleum Gas (LPG) by stabilizing the hydrogenated hydrocarbons in a gasoline stabilizer column; and producing the olefins by separating ethylene from C2 hydrocarbons using a C2 splitter column and by separating propylene from C3 hydrocarbons using a C3 splitter column.
