The detection of hard X-ray emission from the kilo-parsec scale jet of active galactic nuclei
cannot be interpreted as the synchrotron emission mechanism from the electron distri-
bution responsible for the radio/optical emission. The X-ray emission when interpreted
as the inverse-Compton scattering of cosmic microwave background photons (IC/CMB
process), the Compton spectral component will peak at GeV energy. The non-detection
of significant gamma-ray flux from these large-scale jets by Fermi disfavoured this model,
particularly at low redshifts. Alternately, synchrotron emission from a different electron
population is suggested. However, the X-ray emissions from the jet of AGN at high red-
shift are usually interpreted as IC/CMB process, due to the increase in cosmic microwave
background (CMB) photon density. But, recent Fermi 𝛾-ray flux upper limit estimates
on jet emission from the high redshift source J1510+5702 questions the validity of the
IC/CMB model. In this work, we consider a model where the multi-spectral component
(MSC) emissions from the large-scale jets of AGN is explained using accelerated and
advected electron distributions [1]. The synchrotron emission from these two electron
distribution is capable of interpreting the MSC jet emission from the jet of J1510+5702.
