Abstract
A process for preparing hydrogen chloride includes reacting chlorine with water vapor in an endothermic reaction with heat being supplied in a first process step to give a mixture of hydrogen chloride and oxygen. Then in a second process step, chlorine that has not been reacted in the first process step is converted into hydrogen chloride in an exothermic reaction by the addition of a reducing agent and oxygen formed in the first process step is bound by the reducing agent. An apparatus has first and second reactors for carrying out the process.
Claims26
A process for preparing hydrogen chloride, which comprises the steps of:
- reacting feed gases, being chlorine with water vapor, in an endothermic reaction with heat being supplied in a first process step to give a mixture of hydrogen chloride and oxygen;
- and
- converting, in a second process step, the chlorine which has not been reacted in the first process step into hydrogen chloride in an exothermic reaction by adding a reducing agent and the oxygen formed in the first process step being bound by the reducing agent.
An apparatus for preparing hydrogen chloride, comprising:
- a first reactor having heating for reacting chlorine with water vapor being starting materials in an endothermic reaction with heat being supplied in a first process step to give a mixture of hydrogen chloride and oxygen;
- a second reactor having cooling for converting, in a second process step, the chlorine which was not reacted in the first process step into hydrogen chloride in an exothermic reaction by adding a reducing agent and the oxygen formed in the first process step being bound by the reducing agent, said first reactor being connected to said second reactor;
- and
- at least one facility for introducing the reducing agent being disposed in a region of connection between said first and second reactors.
