We have analyzed the two blazars of 3C 454.3 and CTA 102 using all available
COMPTEL data from 1991 to 1999. In the 10-30 MeV band, emission from the
general direction of the sources is found at the 4$\sigma$-level, being
consistent with contributions from both sources. Below 10 MeV only 3C 454.3 is
significantly detected, with the strongest evidence (5.6 $\sigma$) in the 3-10
MeV band. Significant flux variability is not observed for both sources, while
a low emission is seen most of the years in the 3-10 MeV light curve for 3C
454.3. Its time-averaged MeV spectrum suggests a power maximum between 3 to 10
MeV.
