摘要： A process and apparatus for oxidizing methanol in a gas stream into formaldehyde in a fixed bed reactor. The process first introduces a gas stream into a fixed bed reactor. The fixed bed reactor contains a catalyst bed having a depth, a width, a length, an inlet, an upstream region, a downstream region and an outlet. Preferably, the inlet, the upstream region, the downstream region and the outlet are provided in the order stated. A vanadia-titania catalyst is provided in the upstream region and a molybdena-titania catalyst is provided in the downstream region. The vanadia-titania catalyst in the upstream region is substantially free of MoO3 and initially (i.e., during oxidation some V2O5 may sublime and migrate to the downstream region) the molybdena-titania catalyst in the downstream region is substantially free of V2O5. Next, the gas stream is contacted with the vanadia-titania catalyst under oxidizing conditions. Then, the gas stream is contacted with a molybdena-titania catalyst under oxidizing conditions which provides a product stream containing formaldehyde at the desired conversion and formaldehyde selectivity.

摘要： Disclosed is a method of coating a catalyst to a support for use in acrolein oxidation reaction. Metallic salt components of the catalyst including molybdate, vanadate and tungstate are dissolved in a liquid to form a suspension of particles of the catalyst. The precipitation of the catalyst particles is controlled by homogenizing the catalyst particles suspended in the liquid. The phase separation between the catalyst particles and the liquid can be substantially slowed down by the homogenization. Then the catalyst is coated on an inert support by applying the suspension of the catalyst particles to the support. In the suspension, the total weight of water is about 0.8 to about 5 times of the total weight of the metallic salts in the catalyst. This method of preparing suspension minimizes the amount of the liquid required to dissolve the metallic salts, which reduces the amount of time and energy to be used in evaporating the liquid from the suspension. Additionally, in obtaining catalyst from the suspension prepared by this method, it is possible to avoid the deterioration of the catalytic performance since less heat is required to evaporate the water.
摘要翻译：公开了将催化剂涂布到用于丙烯醛氧化反应的载体上的方法。包括钼酸盐，钒酸盐和钨酸盐在内的催化剂的金属盐组分溶解在液体中以形成催化剂颗粒的悬浮液。通过使悬浮在液体中的催化剂颗粒均质化来控制催化剂颗粒的沉淀。催化剂颗粒和液体之间的相分离可以通过均化显着减慢。然后通过将催化剂颗粒的悬浮液施加到载体上将催化剂涂覆在惰性载体上。在悬浮液中，水的总重量为催化剂中金属盐总重量的约0.8至约5倍。这种制备悬浮液的方法使溶解金属盐所需的液体量最小化，这减少了用于从悬浮液蒸发液体的时间和能量的量。此外，在从通过该方法制备的悬浮液中获得催化剂的情况下，可以避免催化性能的劣化，因为需要较少的热量来蒸发水。

摘要： A molybdenum-based precipitate is prepared according to a process including the first step of forming a crude precipitate by pH adjustment to 6.5 or less in the presence of an alkali metal compound, and the second step of dissolving the crude precipitate in aqueous ammonia and forming a precipitate by pH adjustment to 6.5 or less. Then, the resulting molybdenum-based precipitate is washed with an acid aqueous solution having a pH of 6.5 or less and containing not less than 0.01 mole/L of ammonium root. Thus, a change in average particle diameter can be suppressed and good workability can be achieved, so that a molybdenum-based precipitate having a high purity and a desired average particle diameter can be obtained.

The catalyst is prepared by recycling a spent catalyst discharged from a hydro-desulfurization process of an oil refinery in which the spent catalyst comprises an alumina support (preferably, gamma alumina) with a large specific surface area impregnated with high contents of vanadium. The spent catalyst is mixed with a tungsten-impregnated titania, whereby a catalyst comprising suitable metal components and a mixture support of alumina and titania may be prepared. The catalyst in accordance with the present invention has excellent dioxin removal performance and low preparation cost because of recycling the spent catalyst.
