Abstract: Nitrobenzene is reduced to aniline with hydrogen under elevated temperatures and pressure in the presence of a catalyst containing 0.1 to 10 percent by weight palladium and 0.1 to 5 percent by weight vanadium or a compound of vanadium on an aluminum oxide support wherein at least 20 percent thereof has been converted into lithium-aluminum spinel.

Abstract translation: 在含有0.1至10重量％钯和0.1至5重量％钒的氧化铝载体上的催化剂存在下，在升高的温度和压力下将硝基苯还原为苯胺，其中至少20％ 已经转化为锂铝尖晶石。

Abstract: Process for the complete saturation of a stream containing C2 to C4 hydrocarbons by hydrogenating such in a trickle phase over a fixed bed noble metal catalyst in the presence of a hydrogen atmosphere wherein about 0.3 to 3 parts of hydrogenation products per part of fresh feed are recycled in the process.

Abstract: HYDROGENATION OF PYROLYSIS GASOLINES OR FRACTIONS THEREOF IN A FIRST STEP AT A TEMPERATURE BELOW ABOUT 100* C. TO HYDROGENATE SELECTIVELY SUBSTANTIALLY THE DIOLEFIN CONTENT THEREIN, AND THEREAFTER IN A SECOND STEP OF THE HYDROCARBON MIXTURE OBTAINED FROM THE FIRST STEP AT A TEMPERATURE ABOVE 100*C., E.G. AT ABOUT 150-250*C., TO HYDROGENATE SELECTIVELY SUBSTANTIALLY THE MONO-OLEFIN CONTENT THEREIN, BOTH STEPS USING NOBLE METAL ON AN ALUMINUM SPINEL SUPPORT AS HYDROGENATION CATALYST, AT A HYDROGEN PRESSURE OF ABOUT 20-80 ATMOSPHERES, PREFERABLEY IN A SUBSTANTIALLY STATIC HYDROGEN ATMOSPHERE, AND OPTIONALLY WITH RECYCLING OF HYDROGENATION PRODUCT TO THE HYDROGENATION REACTOR.
