In this paper we study the acceleration of protons and electrons by turbulent plasma waves generated via MRI or/and magnetic reconnections in hot accretion tori around black holes, ranging from stellar mass ones in X-ray binaries to supermassive black holes in AGNs. Energy loss processes dominated at different energy ranges and under different physical conditions are reviewed. Emphases are then put on the acceleration to relativistic energies of electrons and protons from a thermal background with a temperature close to the virial value, their radiative signatures, and their possible connections to the formation of relativistic outflows. We investigate the dependences of model predictions on the size of the acceleration site, which is proportional to the black hole mass, the gas density, which depends on the mass accretion rate, and the energy partitions between the magnetic field, the turbulence, and the thermal energy of the plasmas for a general spectrum of the turbulent plasma waves.
