Process for the production of caboxylic acids and carbonyl compounds by utilizing carbon dioxide-rich feedstock

A method of producing one or more of alcohols, carboxylic acids, carbonyl compounds, and carbonates, the method comprising:

• a) producing a syngas via a short contact time catalytic partial oxidation process which uses a feedstock comprising an organic component and an inorganic component, wherein:
• i) the organic component is a mixture comprising carbon dioxide included in one or more of natural gas, off-gases of industrial chemical or refining activities, and blast furnace gases, coke oven gases, direct reduction gases produced in the reduction of iron ores activities, biogas and carbon dioxide captured from gaseous streams, the carbon dioxide being from 1 to 50% v/v of the mixture;
• ii) the inorganic component comprises one or more of air, oxygen, and air enriched with oxygen, the oxygen being obtained from electrolysis of water or from air;
• iii) the short contact time catalytic partial oxidation process is carried out in a reactor comprising a first portion having a cylindrical shape including a mixing inlet zone and a first thermal preheating shield zone, a second portion having a truncated cone shape containing a catalytic bed, and a third part having a cylindrical shape with a diameter greater than the diameter of the first cylindrical portion, including a second thermal shield zone and a reactor exit zone, wherein:
• a. the first thermal shield zone is pre-heated at a temperature from 50 to 450° C.;
• and
• b. the short contact time catalytic partial oxidation is carried out on the catalytic bed at a gas hourly space velocity from 15,000 to 500,000 h−1 and at a pressure from 1 to 60 atm;
• iv) whereby the syngas obtained from the reactor has a hydrogen/CO ratio from 0.5 to 2;
• b) using the syngas for the production of a compound selected from the group consisting of carboxylic acids, alcohols, carbonyl compounds, and carbonates.
