Method For The Preparation Of Synthesis Gas

Patent No. EP3658495 (titled "Method For The Preparation Of Synthesis Gas") was filed by Haldor Topse on Jul 20, 2018. The application was issued on Aug 30, 2023.

Patent Summary

A method for preparing synthesis gas comprises: (a) providing a hydrocarbon feedstock; (b) generating separate hydrogen and oxygen streams via water/steam electrolysis; (c) tubular steam reforming at least part of the feedstock; (d) autothermal reforming (ATR) the tubular reformed gas using at least part of the electrolytic oxygen to produce a stream of $\text{H}_2$, $\text{CO}$, and $\text{CO}_2$; (e) introducing at least part of the electrolytic hydrogen into the ATR gas stream; and (f) withdrawing synthesis gas. Electrolysis is operated such that all produced hydrogen is added downstream of step (d) to achieve a synthesis gas module $M = (\text{H}_2 - \text{CO}_2)/(\text{CO} + \text{CO}_2)$ between 1.9 and 2.2, preferably 2.0 to 2.1. Optional air separation may provide additional oxygen to the ATR.
