DESCRIPTION:Carlo Giorgio Visconti Politecnico di Milano\, Deparment of En
 ergy - Via La Masa 34\, 20156 Milano (Italy)\nThe availability of excess r
 enewable power and the need of reducing the CO2 footprint of energy and ch
 emical processes brought about new opportunities for the production of Cne
 utral fuels and chemicals. This work presents three alternative catalytic 
 processes studied in the last few years at Politecnico di Milano that can 
 potentially use recovered CO2 and renewable H2 to synthetize gaseous or li
 quid fuels with a wide marked and/or added-value chemicals. The first tech
 nology considered exploits a Ru-based catalyst to make synthetic natural g
 as out CO2/H2 mixtures [1]. Our main contributions to the field has been t
 he\ndescription of the process kinetics in a wide range of process conditi
 on relevant to industrial operations and the analysis of mass transport li
 mitations for catalyst pellets suitable to be used in technical fixed bed 
 reactors. The second process considered aims at converting CO2/H2 mixtures
  in liquefiable (LPG) or liquid (diesel and gasoline) fuels. To this aim\,
  Fe- and Co-based catalysts are used and operations under pressure are car
 ried out [2]. Our attention has been\nfocused in this case on the catalyti
 c aspects driving the process selectivity and the possibility to modify th
 e catalyst properties so to tailor the obtained products. The third proces
 s considered is again based on Fe-based catalysts\, which have been modifi
 ed in this case to maximize the yield to C2-C4 olefins\, the well-know bui
 lding-blocks of the petrochemistry sector [3]. Our interests were concentr
 ated in the catalysts design\, which has to be optimized so to limit the\n
 formation of either methane and C5+ species\, while boosting the synthesis
  of unsaturated hydrocarbons at the same time.\n\nReferences:\n[1] L. Falb
