摘要: Methods, apparatus and processes for three phase contacting and reactions in a cross flow reactor with reduced feed vaporization, low pressure operation, higher liquid holdup, lower reactor pressure drop, low severity operation, and reduced product inhibitory effects. A cross flow reactor for three phase catalytic hydroprocessing, having at least one reactor stage is disclosed. The reactor stage has a central gas distributor with perforated lateral surface for distributing gas, a middle region accommodating a packed catalyst bed, and an outer gas space for removal of effluent gases from the middle region. The middle region receives a liquid reactant and gas from central gas distributor to carry out three phase catalytic hydroprocessing reaction.
