Abstract
Description
測定温度範囲:20℃〜300℃
増温速度:10℃/分
水素:30ml/分
圧力:常圧
処理剤量:5〜15mg
本発明の除害剤における還元安定性の測定結果は表2に示す。
除害性能測定装置:常圧流通式反応装置
反応管のサイズ :内径28mm、長さ700mm
測定条件
使用処理剤量:60cc(充填高さ100mm)
GHSV :300hr−1
圧力 :常圧
反応温度 :常温
反応ガス組成:SiH4(シラン)、又はPH3(ホスフィン)、
N2 バランス
除害剤60ccを充填高が100mmになるように反応管内に詰めて測定装置に設置し、次いで窒素(純度99.99%)で希釈した金属水素化物ガスを除害剤充填層に流通させた。ガス流通開始後、除害剤層の温度測定を行いつつ、反応管出口ガス中への金属水素化物ガス漏洩をブレークモニター(日本バイオニクス製)で測定、監視し、その出口濃度が5ppmに達するまでに流入したシラン、ホスフィン、ゲルマンの積算量を求め、その量を処理剤1kg当りに換算した。具体的には測定結果から次の式によって金属水素化物ガスの除害性能は計算された。
除害性能(L/kg)=A×(B/100)×(C/E)
ここで、A:測定ガス流量(L/min.)
B:金属水素化物ガス濃度(容積%)
C:金属水素化物ガスの出口濃度が所定の濃度に達するまでの累積ガス流通時間(min.)
E:処理剤充填量(kg)
