For extremal charged black holes in any dimension and with any cosmological constant, a fine-tuned near-horizon particle collision can eject a particle carrying arbitrarily large, though finite, energy.

abstract
We argue that the possibility of having infinite energy in the centre of mass frame of colliding particles is a generic property of rotating black holes. We suggest a general model-independent derivation valid for "dirty" black holes. The earlier observations for the Kerr or Kerr-Newman metrics are confirmed and generalized.

Penrose and super-Penrose energy extraction from a Reissner-Nordstr\"om black hole spacetime with a cosmological constant through the BSW mechanism: Full story
For extremal charged black holes in any dimension and with any cosmological constant, a fine-tuned near-horizon particle collision can eject a particle carrying arbitrarily large, though finite, energy.
