We discuss some theoretical aspects of pickup ion acceleration at the solar wind termination shock and beyond in the heliosheath. Our model of anisotropic transport permits a wide range of acceleration mechanisms, including (a) adiabatic compression by the shock of PUI suprathermal tails, (b) standard diffusive acceleration at the shock, (c) mirroring by the magnetic field kink at a quasi-perpendicular shock, and (d) momentum diffusion in the solar wind and the heliosheath. It is shown that momentum diffusion in the heliosheath is an efficient particle accelerator at low energies. We also investigate the processing of a pre-accelerated pickup ion spectra by the termination shock and analyze the long-term averaged anisotropies of the combined distributions near a shock whose obliquity varies with time.
