Process and system for conversion of carbon dioxide to carbon monoxide

摘要

A process and an apparatus for converting carbon dioxide CO2 into carbon monoxide CO using hydrocarbons are described. In further embodiments, processes and apparatuses for generating synthesis gas and processes and apparatuses for converting synthesis gas into synthetic functionalized and/or non-functionalized hydrocarbons using CO2 and hydrocarbons are described. The processes and apparatuses are adapted to convert CO2 emitted by industrial processes, and thus the amount of carbon dioxide emitted into the atmosphere may be reduced.

1. A method for converting carbon dioxide CO2 into carbon monoxide CO comprising the following steps:
decomposing a hydrocarbon containing fluid into carbon and hydrogen by means of introduction of energy in a hydrocarbon converter, the energy at least partially being provided by heat, wherein the decomposing step takes place at a temperature above 1000° C. and wherein the carbon and the hydrogen have a temperature of at least 200° C. after the decomposing step; directing at least a portion of the carbon generated by the decomposing step from the hydrocarbon converter into a CO2 converter; introducing CO2 gas from an external CO2 source into the CO2 converter; mixing the CO2 gas with at least a portion of the carbon generated by the decomposing step, wherein upon mixing the carbon with the CO2 gas, the carbon obtained by the decomposing step has cooled down by no more than 50% in ° C. with respect to its temperature after the decomposing step; converting at least a portion of the CO2 gas and the carbon obtained by the decomposing step into CO at a temperature between 800 and 1700° C.
