The results of a Monte Carlo study of a hard X-ray concentrator for space astronomy are presented. This report is a part of a systematic study devoted to investigate the possibility of utilizing the Bragg diffraction technique to concentrate hard X-rays. In the Monte Carlo study a concentrator made of confocal mirrors with paraboloidal shape is considered. The mirror material is graphite (002) with mosaic structure. The main photon interactions of hard X-rays with the concentrator are simulated. Effective area and optical properties of a particular configuration of concentrator with shape that could be easily accommodate on the Space Station or aboard a free-flyer are given. Expected performances are discussed.
