Description
適用されない。
高せん断混合器、又は高せん断ミルなどの高せん断装置(HSD)は一般的にそれらの流体を混合させる能力に基づいて分類される。混合は流体中の不均一な種又は粒子のサイズを減少させる方法である。混合の程度又は完全さの1つの測定基準は、流体粒子を分散させるために混合装置が生み出す単位体積当たりのエネルギー密度である。種類は伝達されるエネルギー密度に応じて区別される。0から50μmの範囲のサイズの粒子又は気泡の混合物又はエマルションを一貫して生産するために十分なエネルギー密度を有する3種類の工業用混合器がある。
高せん断装置100、以下HSS100、は液体芳香族炭化水素を水素化することに適している。本開示の方法及びシステムは今ベンゼン水素化の速度を加速させるための方法及びシステムに関連して説明されている。図2は多相反応システムを使用して且つ高せん断装置を備えるベンゼン水素化方法のフロー図である。以下に更に説明するように、高せん断装置を用いる開示された方法は多相間の物質及び熱移動の抵抗を減少させる。図2はポンプ5、高せん断装置40、及び反応器10を備える代表的な高せん断多相反応システムの基礎的な構成要素を示している。
