Apparatus for reacting solid in lumps with gas, especially for producing chlorosilanes from silicon and hydrogen chloride, has secondary reaction zone on supporting grating(s) below grating of main reaction zone

摘要

Apparatus for reacting solids in lumps with a gas has secondary reaction zone, in the form of other supporting grating(s), below the supporting grating of the main reaction zone. An independent claim is also included for a process for reacting silicon metal with hydrogen chloride gas in such a fixed-bed reactor.
