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.

Abstract: The invention relates to a method for the catalytic production of melamine by the decomposition of urea in particular on solid catalysts using a main and post reactor. A catalyst of low Lewis acidity is employed in the main reactor and in the post reactor a catalyst is employed with the same or preferably a greater Lewis acidity.

Abstract: Disclosed is a fluidized bed reactor for carrying out a gas phase reaction. A gaseous reaction mixture flows from the bottom to the top of a heterogeneous particulate catalyst that forms a fluidized bed in which baffles are arranged. Said fluidized bed reactor is characterized in that the baffles divide the fluidized bed into a plurality of cells horizontally disposed in the fluidized bed reactor and a plurality of cells vertically disposed in the fluidized bed reactor, the cell walls being gas-permeable and being provided with openings which ensure that the heterogeneous particulate catalyst reaches a transfer rate ranging from 1 to 100 liters/hour per liter of reactor volume in the vertical direction.
