  In this paper we present a detailed comparison of the bottom production in
gluon -- gluon, photon -- gluon, photon -- photon, pomeron -- gluon, pomeron --
pomeron and pomeron -- photon interactions at the LHC. The transverse momentum,
pseudo -- rapidity and $\xi$ dependencies of the cross sections are calculated
at LHC energy using the Forward Physics Monte Carlo (FPMC), which allows to
obtain realistic predictions for the bottom production with one or two leading
intact protons. Moreover, predictions for the the kinematical range probed by
the LHCb Collaboration are also presented. Our results indicate that the
analysis of the single diffractive events is feasible using the Run I LHCb
data.
