Production method of single ring aromatic hydrocarbon and production plant of single ring aromatic hydrocarbon

摘要

As for this invention, 10 capacity % distillation temperature above the 140 and 90 capacity % making with the raw materials oil and the aromatic production catalyst contact where distillation temperature is below the 380, being production method of the single ring aromatic hydrocarbon which produces the reaction product which includes the single ring aromatic hydrocarbon, the aforementioned raw materials oil, the disassembly improvement reactor which accommodates the aforementioned aromatic production catalyst (10) process and the aforementioned disassembly improvement reactor which are introduced (10) process and the aforementioned raw materials oil which make the aforementioned raw materials oil contact with the aforementioned aromatic production catalyst in inside the aforementioned disassembly improvement reactor (10)Before introducing inside, heating the aforementioned raw materials oil beforehand, gas-liquid partition stage and the aforementioned vapor fraction and the aforementioned liquid fraction which for the vapor fraction and the liquid fraction gas-liquid are separated the respective aforementioned disassembly improvement reactor (10) the introduction process which is introduced into the position where the inside differs mutually and, it has heating process and the aforementioned gas-liquid mixtures style which form gas-liquid mixtures style.
