図1に図示されている分解装置および分解工程の流れでフェノール系副産物の分解を実施した。具体的には、下記の表1の組成を有するフェノール系副産物を総段数が30段である反応性多段蒸留カラム10の側面に備えられた流入口に供給し、フェノール系副産物(流量:1000kg/hr)の熱分解(熱分解温度:330℃、熱分解圧力:常圧)を実施した。
図2に図示されている分解装置および分解工程の流れでフェノール系副産物の分解を実施した。具体的には、下記の表1の組成を有するフェノール系副産物を総段数が30段である反応性多段蒸留カラム10の側面に備えられた流入口に供給し、フェノール系副産物(流量:1000kg/hr)の熱分解(熱分解温度:330℃、熱分解圧力:常圧)を実施した。
図3に図示されている分解装置および分解工程の流れでフェノール系副産物の分解を実施した。具体的には、下記の表1の組成を有するフェノール系副産物を反応器100に供給し、フェノール系副産物(流量:1000kg/hr)の熱分解(熱分解温度:330℃、熱分解圧力:常圧)を実施した。前記熱分解により、タールを含むストリームは反応器100の下部に、有効成分とアセトフェノンを含むストリームは反応器100の上部に排出された。この際、前記熱分解により、フェノール系副産物に含まれたアセトフェノンの約99重量%が反応器100の上部に分離され、フィード(feed)重量の約30重量%に相当するタールが生成された。
図4に図示されている分解装置および分解工程の流れでフェノール系副産物の分解を実施した。具体的には、下記の表1の組成を有するフェノール系副産物を反応性多段蒸留カラム300に供給し、フェノール系副産物(流量:1000kg/hr)の熱分解(熱分解温度:330℃、熱分解圧力:加圧)を実施した。前記熱分解により、アセトフェノンとタールを含むストリームは反応器300の下部に、有効成分を含むストリームは反応器300の上部に排出された。この際、前記熱分解により、フェノール系副産物に含まれたアセトフェノンの約99重量%が反応器300の下部に分離され、フィード(feed)重量の約30重量%に相当するタールが生成された。
図5に図示されている分解装置および分解工程の流れでフェノール系副産物の分解を実施し、有効成分を反応器400の側面から分離し、ライト成分を反応器400の上部から分離すること(有効成分とライト成分を別個に分離)以外は、前記実施例1と同じ過程でフェノール系副産物の分解を実施した。
前記実施例および比較例により得られた有効成分の組成および熱分解過程で消費した熱エネルギー(heaterの運転に消耗したエネルギー)を確認し、その結果を下記表2に示した。
