Systems and processes for lipid feedstock treatment with moving bed reactor

A lipid feedstock including fatty acid(s) is treated in a process flow through a moving bed reactor with catalyst to produce a treated stream. The catalyst may include metal oxide catalyst on a particulate oxide support. The catalyst may be transferred, using a catalyst withdrawal line, from the bottom of the moving bed reactor to a fluidized bed regenerator, and regenerated. The catalyst may be transferred from the fluidized bed regenerator to a cyclone that separates the catalyst from flue gas. The catalyst may be transferred from the cyclone to the top of the moving bed reactor using a catalyst feed line. A first separation gas may be flowed into the catalyst feedline, and a second separation gas may be flowed into the bottom of the moving bed reactor or into the catalyst withdrawal line, to generate pressure differentials driving the process flow through the moving bed reactor.
