The Method for Avoidance of Palladium/Carbon Catalyst Poisoning and Its Commercial Application

After utilizing an improved method for adding a non-precious promoter to the precious Pd/C catalyst during hydrogenation of benzoic acid, a new understanding concerning regeneration of deactivated Pd/C catalyst has been obtained, and an improved process has emerged. The improved process can avoid the conventional technical shortcomings related with hydrogenation of benzoic acid such as the quick decline of catalyst activity in a relatively short period of time and low palladium recovery from the spent catalyst. Furthermore, according to this process, cyclohexane carboxylic acid （CCA） can be produced Pavorably in a commercial scale at a high selectivity and product yield with a extended catalyst life.     

Development and Commercial Application of Supported Palladium Catalyst for Isomerization of C5/C6 Hydrocarbons

1 Introduction. China has enforced a new gasoline standard starting 2003 to limit the olefins, aromatics and benzene contents in gasoline. The isomcrate is the cleanest gasoline component because it does not contain the above-mentioned components, and is also an excellent gasoline blending component because of its higher RON and MON ratings. Currently the FCC naphtha accounts for 81.4% of gasoline pool, reformate accounts for 12.6% of gasoline pool, MTBE makes up 4% of gasoline pool.

A new type of zeolite La-USL (ultra stable zeolite L (zeolite USL) modified by La), which has superior activity, stability and selectivity in catalytic cracking of hydrocarbons and thus can be used as an active catalyst component, is reported in this paper. The zeolite L with relative crystallinity of above 90% was synthesized by the hydrothermal crystallization method under optimum conditions and characterized by means of XRD, NH3-TPD and isotherm adsorption techniques. The in-situ synthesized zeolite L with a SiO2/Al2O3 mole ratio of 5-6 was modified by cation ion exchange, hydrothermal dealumination and chemical modifications with La in order to prepare La-containing USL with a higher framework SiO2/Al2O3 mole ratio of 15-30. The modified zeolite La-USL was used as an active additive component of fluid catalytic cracking (FCC) catalyst and the resulting catalysts were evaluated by microactivity test (MAT) and fixed-fluidized bed (FFB) experiments using heavy oil as feedstock. The influence of La content in La-USL on cracking product distribution, gasoline group composition and research octane number (RON) was investigated. The results showed that when La content in La-USL was 0.8 wt%, the addition of the corresponding La-USL could result in a FCC catalyst that produced significant improvement in product distribution and gasoline quality.
