Method of controlling the reaction process by the adjustment method and the method of adjusting the raw material concentration in the gas phase catalytic reaction process, as well as the method of manufacturing a lower fatty acid ester or lower fatty acids using the control method

摘要

To the process by the value in the adjustment of the raw material concentration in the supplied gas (57) to the reactor in a gas phase catalytic reaction process having SUMMARY recycle system, by measuring the concentration of the source gas in the process, it was determined that method of adjusting the raw material concentration, including that of supplying for a fixed amount of supply of raw materials to be newly added to control the concentration of the source gas supplied in the result reactor and method of controlling a reaction process with the adjustment method.
