Two-dimensional model agglomerates were formed by successive addition of uniform discs to a core using a Monte Carlo simulation procedure. Whether the addition of a disc occurred or not was determined by comparing the pseudo-random number generated at every collision between a disc and the core with the cohesion probability P (method I). The porosity of agglomerates and the average coordination number were calculated. Another method of the formation of two-dimensional agglomerates were by placing discs of equal size at the fixed position of a rhombic lattice. The process was begun with a disc placed at the center of the lattice and the growth of the agglomerate proceeded toward the outer layers. In this treatment the packing probability Q was taken into consideration (method II). The compaction of the agglomerate, that is the reduction of porosity, was simulated by inserting discs into the vacant position of the lattice with the probability of Q'. The compaction kinetics were investigated using Kuno and Kawakita equations.
