摘要： A process by which the raw material, a gas comprising mainly hydrogen, carbon monoxide and carbon dioxide, is introduced into a first reactor together with a catalyst, in which one or more reactions take place that produce methanol or dimethyl ether or both, which are then introduced into a second reactor adding oxygen and a catalyst and producing formaldehyde and a minority of dimethyl ether, and where there may be an excess of water, such water being extracted from the process and the remaining products being introduced into the third reactor with, optionally, an additive, and such raw material is exposed to catalysts and under an atmosphere at medium temperature and pressure, in order to produce three or four groups of chemical reactions that, after extracting most of the water that is generated as a residue during the process, produces as a result a liquid multifunctional product that can be used as a solvent, a foaming agent or an oxygenated fuel; said product, normally a fluid, comprises polyoxymethylene dimethyl ethers with molecular formula CH3O(CH2O)nCH3 wherein n has a value between 1 and 7.

摘要： An object of the present invention is to provide a catalytic gas phase oxidation reaction in which: even under reaction conditions of a higher gas pressure, a higher concentration of the raw material gas and a larger space velocity of a reaction gas, the thermal accumulation at the hot spot portion can be sufficiently suppressed with ease and at low costs, so that the reaction can be continued for a long time while a high yield is maintained. As a means of achieving this object, a catalytic gas phase oxidation reaction according to the present invention is a catalytic gas phase oxidation reaction with molecular oxygen or a molecular-oxygen-containing gas by using a fixed-bed multitubular reactor packed with catalysts; with the catalytic gas phase oxidation reaction being characterized in that: a catalyst-packed layer of each reaction tube of the reactor is divided into at least two reaction zones in a tubular axial direction; and the packing of the catalysts is such that the occupation volumes of the catalysts differ between at least two of the reaction zones and that an inert substance molding is mixed in at least one of the reaction zones.
