Activities of Copper Chromite Catalysts for Dehydrogenation of Ethanol
The Journal of the Society of Chemical Industry, Japan, 1970 脱水素用亜クロム酸銅系触媒の活性究明の一助とするために, 純エタノールの脱水素反応に対して, 細孔内拡散の影響度を考慮した速度評価を行なった。すなわち, 工業用円柱触媒 [A,(CuO-Cr2[CuO4]系);径:0.490～0.495cm, 高さ:0.217～0.407cmとG-13,(Cr2[CuO4]系);径:0.476～0.479cm, 高さ:0.215～0.285cm]のそれぞれ, 代表寸法(ΣVpi/ΣSOi;ΣVpi:見かけ容積の和,ΣS0i:見かけ外表面積の和)の異なるものに対して, 触媒Aは 200～300℃で, 触媒 G-13 は 200～350℃ で, 常圧・等温流通系操作によって, 触媒見かけ単位容積当りおよび単位質量当りの, 外部抵抗の無視できる場合の定常速度 (ra ...

Some unusual observations concerning the adsorption of thiophene on copper chromite
, 1979 Adsorption of thiophene, a poison, on copper chromite catalyst has been studied at conditions close to those used in the reduction of nitrobenzene to aniline (i.e., at temperatures of 150° to 300°C and in the presence of excess hydrogen) by using pulse ...

The effect of a copper sulphate addition on the recovery of chromite in the flotation of UG2 Ore
, 2015 Chromite and talc are two major gangue minerals in platinum bearing UG2 ore processed from the Bushveld Complex in South Africa. During flotation, talc is effectively depressed by the addition of depressants. Chromite, on the other hand, is considered to
