Title

Abstract
(EN)
A process for producing a compound containing carbon and S, in particular, a process for producing carbon disulfide by circulating fluid bed is provided, to solve the problems of high energy consumption, process discontinuity, serious environmental pollution and so on in the processes of the prior art. In the process, the carbon-containing solid matter is added into a fluid bed heating oven; the heated carbon-containing solid matter enters a pre-lifting device, a lifting pipe and a fluid bed, then contacts and reacts with sulfur; the carbon disulfide vapor is separated by a fast separating device and a settling vessel; the remained unreacted carbon-containing solid matter falls into the stripping section under the settling vessel; and then returns to the fluid bed to be heated after being stripped off the entrained carbon disulfide by inert gas. The process has the following advantages: the contact efficiency of the reactants is improved greatly; the required temperature is lower and the equipment is simple because sulfur may be used in liquid state; the pollution is reduced and the yield of production is increased by providing the stripping section; the equipment is simple in the structure, inexpensive and suitable for continuous and automatic production and environmental treatment.

Procédé de préparation d'un composé à base de carbone et de soufre pour la préparation de disulfure de carbone par lit fluidisé circulant permettant de remédier aux problèmes de consommation d'énergie, de discontinuité dans le processus de fabrication et de pollution présents dans l'art antérieur. Un four à lit fluidisé est alimenté en solides contenant du charbon, lesquels sont ensuite introduits successivement dans un dispositif de pré-relevage, dans un tuyau de relevage puis dans un lit fluidisé avant d'entrer en contact et de réagir avec le soufre. La phase gazeuse du disulfure de carbone est extraite par un séparateur rapide et un décanteur, les solides contenant du charbon n'ayant pas réagi retombent dans la partie de décapage située sous le décanteur, puis retournent vers le lit fluidisé afin d'être chauffés après décantation du disulfure de carbone par un gaz inerte. L'invention permet une meilleure réactivité des réactifs, améliore de manière simple et peu coûteuse le rendement, la continuité et l'automatisation de la production d'une part et permet d'autre part une production plus respectueuse de l'environnement.
