1. A method, comprising:
(a) directing an olefin feed stream comprising (i) ethylene (C2H4) at a concentration of at least about 0.5 mole percent (mol %), (ii) propylene (C3H6) and (iii) carbon monoxide (CO) or carbon dioxide (CO2), into an ethylene-to-liquids (ETL) reactor, wherein said ETL reactor comprises an ETL catalyst that facilitates conversion of C2H4 to higher hydrocarbon products, wherein said ETL reactor operates substantially adiabatically, wherein said olefin feed stream has a combined concentration of C2H4 and C3H6 of at most about 10 mol %, and wherein said olefin feed stream is at a first temperature; (b) in said ETL reactor, conducting an ETL process to convert said C2H4 in said olefin feed stream to said higher hydrocarbon products as part of a product stream at a second temperature, said higher hydrocarbon products including (i) at least 5 compounds having 5 different carbon numbers, said 5 carbon numbers selected from 12 through 20 and (ii) a paraffin compound, an isoparaffin compound, and a naphthene compound, which second temperature is higher than said first temperature, and wherein said ETL process liberates heat; and (c) recovering from said product stream a liquid stream comprising said higher hydrocarbon products including (i) at least 5 compounds having 5 different carbon numbers, said 5 carbon numbers selected from 12 through 20, wherein each of said 5 carbon numbers is at a concentration of at least 5 weight percent (wt %) of said liquid stream, and (ii) a paraffin compound, an isoparaffin compound, and a naphthene compound, wherein at least about 80% of said heat liberated in said ETL process provides a difference between said first temperature and said second temperature of between about 50° C. and about 150° C. |
