Embodiments of methods and apparatuses for catalytic reforming of hydrocarbons including regeneration of catalyst are provided. In one example, a method comprises heating an inert gas to form a heated inert gas stream. A first portion of the heated inert gas stream is indirect heat exchanged with hydrogen gas to form a first partially heated inert gas stream and a heated hydrogen gas stream that is for lifting the catalyst; and/or a second portion of the heated inert gas stream is indirect heat exchanged with an organic chloride-containing stream to form a second partially heated inert gas stream and a heated organic chloride-containing stream that is for chlorinating the catalyst; and/or the catalyst is preheated using at least a third portion of the heated inert gas stream for indirect heat exchange with a nitrogen gas stream or using the first and/or second partially heated inert gas streams.
