    Abstract: What is proposed is a process for preparation and distillative processing of diphenylmethane diisocyanate (MDI), proceeding from a benzene-containing feed stream, wherein, in a catalytic hydrogenation of nitrobenzene to aniline, steam is generated at two different pressure levels, which covers some or all of the energy demand for the overall process, by using two fluidized bed reactors of identical design, a first fluidized bed reactor being operated with an aniline charge for which the fluidized bed reactors were designed and providing steam at a first, lower pressure level, and a second fluidized bed reactor being operated with a charge reduced with respect to the first fluidized bed reactor to such an extent that the second fluidized bed reactor provides steam at the higher pressure level.

    Abstract: The present invention relates to a process for the non-oxidative dehydroaromatization of a feed stream containing C1-C4 aliphatics comprising the steps I, feeding the feed stream E into a reaction zone 1, reacting the feed stream E under non-oxidative conditions in the presence of a particulate catalyst to give a product stream P containing aromatic hydrocarbons, and removing the product stream P from the reaction zone 1; II, transferring the catalyst that is reduced in its activity by deposited coke into a reaction zone 2; III, at least partial regeneration of the catalyst with feed of a hydrogen-containing gas stream H in a reaction zone 2, wherein at least some of the deposited coke is converted into methane and a methane-containing gas stream M is formed that is fed at least in part to the reaction zone 1; IV, removing the catalyst from the reaction zone 2 and V, recirculating at least some of the catalyst that is removed to the reaction zone 1, wherein reaction zone 1 and reaction zone 2 are arranged spatially adjacently in the same reactor.
