dc.description.abstractMitigating 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.; Erregai fosilen errekuntzek eragindako klima-aldaketa pairatzea da egungo gizartearen erronka nagusietariko bat. Errekuntza horiek isuritako berotegi-efektuko gasen artean ugariena karbono dioxidoa (CO2) da, haien % 75 inguru. Beraz, honen emisioak murriztea eta dagoeneko isuritakoa bahitzea ezinbestekoa da klima-aldaketak eragindako ingurumen-kaltea ahalik eta gehien murrizteko. Horretarako, ezinbestekoak dira CCU teknologiak (karbono dioxidoaren bahiketa eta erabilera). CO2-a erabiltzen duten prozesuen artean, bihurtze katalitikoak etorkizun laburrean ezartzeko aukera onak ditu. Prozesu katalitikoen artean, ohikoena CO2-aren hidrogenazioa da, hidrokarburoak lortuz. Prozesu honen moldakortasuna da bere ezaugarri interesgarrienetakoa; izan ere, modu hautakorrean hidrokarburo ezberdinak ekoizten dira; besteak beste, olefinak, parafina astunak zein arinak eta aromatikoak. Operazio baldintzak, katalizatzaile motak eta beren ezaugarriak, zein lorturiko CO2-aren balorizazio-mailak ekoiztu nahi den hidrokarburoaren araberakoak dira.
