Un processo per produrre syngas utilizzando CO2 esogena in assenza di combutibili a base di carbonio

A process for producing syngas with an H2/CO ratio of from 0.5 to 3.5, comprising: a) generating steam by burning hydrogen and oxygen in the presence of steam in an H2 burner at a temperature higher than 1000°C, at a pressure comprised between 20 and 40 bar, b) quenching and optionally further cooling the effluents from step a) at a temperature comprised between 800 and 900°C and at a pressure ranging from 20 to 40 bar, preferably 30 bar; c) conducting electrolysis on the steam coming from step b) in a solid oxide electrolytic cell (SOEC) thereby obtaining hydrogen and oxygen, d) cooling wet hydrogen gas coming from step c) and removing water by condensation; e) Carrying out a reverse water gas shift reactor with hydrogen gas coming from step d) with CO2, coming from an external source, thereby obtaining syngas provided that said hydrogen gas is fed to said step in excess of from 0.5 to 3.5 moles, with respect to the stoichiometric molar amount, thereby obtaining wet syngas; f) Cooling wet syngas coming from step e) and removing water by condensation thereby obtaining dry syngas with the required H2/CO ratio.
