  We study the central production of QCD instantons at hadron colliders in
events with two large rapidity gaps. These gaps in rapidity are formed by
either Pomeron or photon exchanges or a combination of the two. The
kT-factorization formalism is used to reduce the factorization scale
dependence. We compute for the first time the relevant differential
cross-sections for a complete set of central instanton production processes at
the LHC, including gluon-induced and quark-induced amplitudes, and also show
that the largest contribution comes from processes with Pomeron exchanges where
a single gluon from each Pomeron couples to the instanton.
