CO2-aren balorizazio zuzena hidrokarburoak ekoizteko

Abstract

Mitigating the climate change caused by fossil fuels burning is one of the major challenges of today’s society. The most abundant (75 %) of the greenhouse gases emitted by these combustions is carbon dioxide (CO2). Therefore, reducing its emissions and capturing what already has been emitted, known as CCU (Carbon dioxide Capture and Utilization) technology, is essential for minimizing the environmental damage caused by climate change. Among the processes that use CO2 as a feedstock, its catalytic conversion has good potential for implementation in the short term. Among the catalytic processes, the most common is its hydrogenation to obtain hydrocarbons. One of the most interesting features of this process is its versatility, as different hydrocarbons can be selectively produced; such as olefins, heavy paraffins or aromatics. The operating conditions, types of catalysts and their characteristics, as well as the CO2 conversion degrees obtained, depend on the hydrocarbons to be produced.
