| titleOfInvention | The anthraquinone method for hydrogenation preparing hydrogen peroxide |
| abstract | The present invention relates to the anthraquinone method for hydrogenation preparing hydrogen peroxide, hydrogen gas and Anthraquinones working solution are passed through in the fluid bed containing rigid granules and carry out described hydrogenation, the pressure of hydrogenation is 0.15～0.35MPa, temperature is 40～75 DEG C, in hydrogenation process, fluid bed keeps bubbling or turbulent flow, and the bus speed of hydrogen gas is 2～30cm/s, and wherein hydrogen accounts for the 40～100% of this volume of gas, remaining is nitrogen, and the settled bed concentration of fluid bed is not less than 0.3g/cm 3 , the density of solid particles in fluid bed is less than 0.3g/cm 3 , particle size distribution range is 20～300 microns, and the anthraquinone concentration in Anthraquinones working solution is 120～200g/L.After using the method for the present invention, production efficiency 40% can be improved on the most domestic fixed bed hydrogenation Process ba-sis, and at production principle and the risk factor substantially solved in producing of technique, product design can be made to be improved more than 40% by 30%, and product quality leading indicator such as organic carbon content, non-volatile content etc. is better than the product that fixed-bed process is produced. |
