Many extended jets of kilo-parsec scale size from Active Galactic Nuclei have been detected by
Hubble and Chandra telescopes. IC/CMB model for X-ray emission from six extended jets has
been ruled out by radio data from ALMA observations and also the predicted gamma ray flux
in this model overshot the Fermi LAT upper limits. We have selected the sources 3C 273, PKS
0637-752, B3 0727+409 and AP Librae for our study. We show the proton synchrotron model
may explain the X-ray emission in some cases without violating luminosity constraints. The kiloparsec
scale jet could be moving with Doppler factor close to 1 in this scenario unlike the IC/CMB
model which requires higher values of Doppler factor to explain the observed emission.
