    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.

    Abstract: The invention relates to a method for producing chlorine by the oxidation of hydrogen chloride with oxygen in a fluidized bed reactor in the presence of a particulate catalyst, the reaction heat produced by the exothermic hydrogen chloride oxidation being carried away by water which circulates in the tubes of a shell-and-tube heat exchanger. The method comprises the following steps: (i) heating the fluidized bed reactor to an operating temperature in the range of 350 to 420°C in a heating phase and (ii) reacting the hydrogen chloride with oxygen at the operating temperature in an operating phase. The method is characterized in that (i-1) the fluidized bed reactor is heated to a temperature below the operating temperature in a first heating phase, and (i-2) hydrogen chloride and oxygen are fed to the fluidized bed reactor and reacted in a second heating phase, the fluidized bed reactor being heated to the operating temperature by the reaction heat produced by the exothermic hydrogen chloride oxidation.

    Abstract: The invention concerns a method for producing chlorine and a hydrochloric gas including the following steps: a) supplying via a stream containing hydrochloric gas (a1) and a stream containing oxygen (a2) an oxidation zone and a hydrochloric gas catalytic oxidation with chlorine, a stream of gaseous product (a3) containing chlorine, water, oxygen, carbon dioxide, and the inert gases obtained; b) cooling the stream of gaseous products (a3) and separating the water from the hydrochloric gas in the form of hydrochloric acid, a gas stream (b) containing chlorine, water, oxygen, carbon dioxide, and the inert gases still remaining; c) optionally drying the gas stream (b), and obtaining a gas stream (c) substantially water-free, containing chlorine, oxygen, carbon dioxide and inert gases; d) liquefying at least partly the gas stream (c) and a return stream (f1) rich in chlorine, containing chlorine, oxygen, carbon dioxide through thickening and cooling, a partly liquefied stream (d) being preserved; e) gas-liquid separation of the stream (d) into a gas stream (e1) containing chlorine, oxygen, carbon dioxide, and inert gases and into a liquid stream (e2) containing chlorine, oxygen, and carbon dioxide; f) introducing at least part of the gas stream (e1) into a unit with membrane and separating a return stream (f1) rich in chlorine and a gas flow (f2) poor in chlorine, containing chlorine, oxygen, carbon dioxide, via a separation by the membrane and reintroducing the return flux (f1) rich in chlorine in step d); g) separating the liquid stream (e2) by distillation into a stream of chlorine (g1) and a stream (g2) comprising substantially oxygen and carbon dioxide.
