摘要： PROBLEM TO BE SOLVED: To produce propylene at a low cost by increasing the yield of the propylene while reducing the deterioration of a catalyst. SOLUTION: Hydrocarbons having 4-6 carbons in each component separated by a separator 12 are returned to a reactor 11 through a pipe 3. On the other hand, low-boiling point compounds having ≤-50°C boiling points in an amount within the range of ≥70% based on the whole amount formed are returned to the reactor 11 through a pipe 2. At least a part of the remainder except the part returned to the reactor 11 through the pipe 2 in the low-boiling point compounds having ≤-50°C boiling points is sent to a low-polymerizer 13 through a pipe 6.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing a lower olefin from a raw material containing dimethyl ether, capable of producing the lower olefin, especially propylene economically in a good yield by inhibiting the carbonaceous substance precipitation on a catalyst for lengthening the time until the temporary inactivation of a zeolite catalyst, also inhibiting the permanent inactivation of the catalyst, reducing the recycling amount of water to improve the thermal efficiency of the process, and also enabling the elimination or marked small-sizing of equipment associated with the recycling of the water and steam generation and the simplification of its operation. SOLUTION: This method for producing the lower olefin is provided by introducing feed gas consisting of raw material gas containing dimethyl ether and diluting gas, and having 5-30 vol.% ratio of steam based on the total amount, into an olefin producing reaction vessel, making a contact with the zeolite catalyst to produce a hydrocarbon product containing 2-5C olefins, recovering/separating propylene, etc., from the obtained hydrocarbon product, and using at least a part of residue obtained by separating the propylene, etc., from the hydrocarbon product, at least as a part of the diluting gas.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing dimethyl ether at low cost by dehydrating methanol by a gas phase reaction using a hydrous low-purity methanol as raw material.
SOLUTION: The method for producing dimethyl ether comprises the following practice: A liquid methanol as the raw material containing e.g. 5-40 wt.% water is vaporized into a gas comprising methanol and water vapor in an evaporator. A refluxing methanol of low water content containing e.g. 1-10 wt.% water is fed in a liquid state to the gas from above the evaporator to effect a countercurrent contact in a gas-liquid contact zone in the evaporator. In this case, part of the water vapor having a higher boiling point than methanol is condensed, while the methanol is vaporized to lower the water vapor concentration of the gas. As a result, the objective dimethyl ether is produced using the hydrous inexpensive methanol as the raw material.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing dimethyl ether at low cost by dehydrating methanol by a gas phase reaction using a hydrous low-purity methanol as raw material.
SOLUTION: The method for producing dimethyl ether comprises the following practice: A hydrous liquid methanol is distilled in a distillation column whose pressure is set higher than that in the latter-stage reactor to obtain a methanol-rich gas, which is then fed into the reactor to synthesize the objective dimethyl ether. The methanol unreacted and water contained in the thus synthesized dimethyl ether are distilled in the distillation column, and the recovered methanol gas is fed to the reactor. In this case, the distillation/refining of the hydrous liquid methanol as the raw material, the preparation of the feedstock gas and the recovery of the unreacted methanol can be performed in the common distillation column. Therefore, running cost can be cut by curbing heat consumption in the whole system and equipment cost can be cut as well.

摘要： PROBLEM TO BE SOLVED: To provide a method for producing aromatic carbonates characterized as (1) changing a reflux ratio in a distillation process during the reaction to rare the energy consumed in the distillation and (2) needing no large-scale production plant. SOLUTION: One version of this method for producing an alkyl aryl carbonate is characterized by comprising transesterification between the corresponding dialkyl carbonate and an aromatic dihydroxy compound; wherein a batch reaction operations is made using a reactor equipped with a distillation section, the reflux ratio in the distillation section is set at lower levels in the early stage of the reaction and then set at higher levels as the reaction proceeds to effect efficient consumption of energy necessary for the distillation. Another version of this method for producing a diaryl carbonate is characterized by comprising disproportionation reaction between a dialkyl carbonate and the corresponding aromatic dihydroxy compound; wherein the reflux ratio in the distillation section is set similarly to the case with the 1st version of this method.
