20130123550 | COPPER HYDROGENATION CATALYST, ESPECIALLY FOR CONVERTING OXALATE TO ETHYLENE GLYCOL, METHOD OF PREPARING THE CATALYST AND APPLICATIONS THEREOF - A copper catalyst for producing ethylene glycol by hydrogenation of an oxalate. The catalyst includes a carrier, an additive, and an active component. The carrier is ceramic or metallic honeycomb. The additive is Al, Si, Ba, Ca, Ti, Zr, Fe, Zn, Mn, V, La, Ce, an oxide thereof, or a mixture thereof. The active component is copper, and the active component and the additive are coated on the carrier to form a coating layer. The additive accounts for 5-90 wt. % of the carrier, the active component accounts for 1-40 wt. % of the carrier, and the copper accounts for 5-50 wt. % of the coating layer. | 05-16-2013 |
20130150617 | MONOLITHIC STRUCTURED CATALYST FOR CARBON MONOXIDE GASE-PHASE COUPLING TO DIALKYL OXALATE & PREPARATION METHOD AND APPLICATION THEREOF - Provided is a monolithic catalyst for synthesizing an oxalate by carbon monoxide (CO) gaseous-phase coupling, a preparation method and the use thereof. In the catalyst, a ceramic honeycomb or a metal honeycomb was used as skeletal carrier, metal oxides were used as a carrier coating, precious metals Pt, Pd, Ir, Rh were used as active ingredients, as well as Fe, Co, Ni were used as additives, wherein the carrier coating accounts for 5 to 50 wt % of the honeycomb carrier the active ingredients of the catalyst account for 0.1 to 5 wt. % of the carrier coating; the additives of the catalyst account for 0.3 to 10 wt. % of the carrier coating; and the atomic ratio of the active ingredients to the additives was 0.1 to 3. the reaction for synthesizing the oxalate was carried out in a fixed bed reactor, wherein, N2 was used as a carrier gas. The volume ratio of N2:CO: Alkyl nitrite was 20-80:5-60:10-40, and the retention time was 0.5-10 s. | 06-13-2013 |
