In this work, we consider a static spherically symmetric charged regular black hole to investigate arbitrarily high centre of mass energy near the horizon with particle collision for extremal case in the equatorial plane ($theta=pi/2$). Here we also study circular geodesics and find the ISCO and MBCO redii. We analysis the two neutral particles collision with same masses and different masses. Also we analyze the particle collision with massless photon and photon-photon collision near the horizon of this regular black hole to calculate centre of mass energy.
