Analysis of the composition of a gas or of a gas stream in a chemical reactor and method for producing chlorosilanes in a reactor fluidized bed

摘要

Procedure for analyzing the composition of a gas or a gas stream containing AlCl3, in a reactor fluidized bed (A) with a height of reactor H0, wherein the HCl fed reacts with silicon, whereby it produce chlorosilanes comprising separation of AlCl3 gas and subsequent analysis of the gas composition by gas chromatography or spectroscopy, characterized in that, because the gas composition is modified a temperature profile in the reactor (a) depending on the reactor height H0 being the temperature profile in the reactor increased turbulent bed S1 (H / H0) = (a1-b1) * (1 / (1 + exp (- c1 ((H / H0) -d1)))) + b1 and less than S2 (H / H0) = (a2-b2) * (1 / (1 + exp (c2 ((H / H0) -d2)))) + b2, where a1 = 100 ° C, a2 = 300 ° C, b1 = 300 ° C, b2 = 400 ° C, c1 = 50, c2 = 20, d1 = 0.2, d2 = 0.8.
