Abstract: A method for reducing CO2 emissions from steam cracking operations can include: introducing an oxygen-rich stream comprising oxygen and from 0 wt % to 15 wt % nitrogen to a vessel; introducing hydrocarbon combustion fuel to the vessel; combusting oxygen and hydrocarbon combustion fuel in the vessel to (1) produce a flue gas comprising carbon dioxide and water and (2) heat a cracking coil passing through the vessel; and performing a steam cracking reaction in the cracking coil passing through the vessel.

Abstract: Systems and methods are provided for forming alkylate from a tertiary alcohol feed. Olefins for the alkylation reaction can be generated from a portion of the tertiary alcohol feed. The tertiary alcohol feed can be obtained, for example, by selective oxidation to convert a portion of an isoparaffin-containing feed into alcohol, such as conversion of isobutane to t-butyl alcohol. The alcohol can then be converted to an alkene, such as conversion of t-butyl alcohol to isobutene, in the alkylation reaction environment in the presence of a solid acid catalyst. The solid acid catalyst can then facilitate dimerization of the alkenes (e.g. isobutene) to form C8+ olefins (e.g. isooctene). A catalyst having an MWW framework is an example of a suitable solid acid catalyst.
