Conversion rate of trichlorosilane in the reduction furnace
Thread Content
Please share the conversion rate of trichlorosilane in the reduction furnace at your companies. Here, it’s around 11.5%; I’m not sure whether that’s considered high or low Is there room for improvement?
There is room for improvement; your 11.5% is considered a moderate level
By adjusting the flow rate of silicon trichloride hydrogen exhaust gas, the residence time of silicon trichloride hydrogen in the furnace can be controlled, which is sufficient to increase its conversion rate
Reply to 2# wzfrank: What is the highest conversion rate of trichlorosilane that can be achieved under ideal conditions?
Reply to 4# ymlgx: Does it mean increasing the air flow speed?
An overall conversion rate of 11.5% is acceptable; during the process, in addition to focusing on the overall conversion rate, attention should also be paid to selectivity. Only by balancing the two indicators can costs be kept at their lowest; it is not sufficient to focus solely on the one-time conversion rate of TCS into Si
Increasing the furnace pressure is the key to solving the problem
I heard that the efficiency of Zhongneng can reach around 20%–30%; I’m not sure if that’s true.
Reply to 9# gcgj568: It’s not that high; the theoretical value is only 28%
Reply to 9# gcgj568: When will the conversion rate of the reduction furnace reach such a high level? Where did this rumor come from?
