ABSTRACT:

The development for practical application of a new production process is made to reduce cost of fuel-use methanol. In the new vapor-phase fluidized bed method, used is a heat exchange type combined reforming furnace where steam reforming and partial oxidation are integrated into one tower in production of synthesis gas (CO, CO2, H2) from natural gas. Part of natural gas is reacted with the oxygen supplied, and using the reaction heat, the remaining natural gas is reformed. For methanol synthesis, a vapor-phase fluidized bed reactor is developed, catalyst particles are fluidized, and reaction heat is recovered as high-temperature steam. In the new production process, increase in plant size and efficiency can be made, and various combinations can be made of the reforming method and the methanol synthesis method. The new production process brings reduction in construction cost, improvement in energy unit requirement, and energy saving. In fiscal 1993, study was made on fluidized bed catalyst, unit process and its optimization, etc. Further, conceptual design was made on high efficiency which is more than 90% in single pass conversion ratio to methanol at 150(degree)C and under less than 30 atm, and an economical low-temperature liquid phase method. 7 refs., 94 figs., 22 tabs.
