Liquid‐to‐particle mass transfer effects in a string pellet minireactor were studied by applying the diffusion‐controlled copper dissolution technique. Structured beds were formed with cylindrical particles in spiral and vertical configurations and operated with liquid and gas‐liquid feeds in upflow mode. Single‐ and two‐phase flow experiments were conducted to study the effects of the gas and the liquid superficial velocities on the liquid‐to‐particle mass transfer coefficient. Computational fluid dynamics calculations were performed to study the effect of the arrangement of the particles in the reactor tube on the liquid‐to‐particle effective mass transfer coefficient for the single‐phase flow. Correlations of the mass transfer coefficient with the operating conditions were derived.
