 nToday\, great attention is attracted to development of highly effective a
 pproaches of converting renewable biomass into energy resources as biofuel
 s. Some spirit compounds\, such as ethanol\, butanol\, pentanol\, glycerin
 e\, being biomass fermentation products\, may be used as fuel components\,
  both without any treatment and after catalytic converting\, that provides
  production of more  effective fuel components. The presented work is devo
 ted to a study of the state and local structure of original nano-dispersed
  catalytic low-percentage systems PdMe (Me=Zn\, Co\, Mn\, Ag) \, used for 
 production of alkanes or olefins fractions С4-С12+ which components of b
 iofuels obtained from biomass fermentation products. Initial samples of ca
 talysts were prepared by impregnation and zol-gel methods from original mo
 no- and hetero-metallic precursors located on the oxide supports. All XANE
 S and EXAFS spectra of the studied samples were recorded at Siberian Synhr
 oton and Terahertz Radiation Center (SSTRC\, Novosibirsk).Genesis of the l
 ocal structure of the studied catalytic nanosystems was characterized in d
 etail. The interatomic distances and corresponded coordination numbers wer
 e revealed. All possible structural models were discussed. Relations betwe
 en their catalytic properties\, local structure distortions and state of m
 etal components were demonstrated. It was found out that active components
  of all studied systems were highly dispersed onto the oxide support surfa
 ce and strong interaction with the support took place\, resulting in forma
 tion of mixed surface MeOx - support oxides. Additionally\, the samples of
  catalysts were characterized by the TEM\, EDX and XPS methods. The data o
 btained by all the methods are in a good agreement. \n\nThe work was done 
 using the infrastructure of the Shared-Use Center “Siberian Synchrotron 
 and Terahertz Radiation Center (SSTRC)” based on VEPP-3 of BINP SB RAS.
