Study on the Performance of Regenerated Catalyst for Ammonoximation of Cyclohexanone

China Petroleum Processing & Petrochemical Technology 2007年第1期9卷 25-30页

作者： Sun Bin Wu Wei Min Enze Xiong Ye Research Institute of Petroleum Processing Beijing 100083 SINOPEC baling Branch company

The study on the deactivated catalyst and the regenerated catalyst for the 70 kt/a cyclohexanone ammonoximation commercial test unit had revealed that addition of a proper amount of silicon additive could suppress the solubilization-induced loss of silicon in catalyst while providing protection to the catalyst. Compared to the direct calcination method for catalyst regeneration, adoption of the regeneration method through pretreatment-calcination of catalyst could be more beneficial to the restoration of catalyst channels and enhancement of the performance of the regenerated catalyst, which could be repeatedly regenerated and utilized. The outcome of commercial scale testing of the catalyst had indicated the good performance of the regenerated catalyst, which could be used for four times, resulting in a reduction of the production cost of cyclohexanone-oxime in big chunks.

PS-PAMAM-IDA chelating resins were prepared by low-generations of polyamidoamine(PAMAM) and then chloroacetic acid functionalizing commercially available ammoniated polystyrene matrix, to preconcentrate Ni2+ from synthetic aqueous samples. Different generations of PAMAM were used to obtain different chelating resins, PS-IDA, PS-1.0G PAMAM-IDA and PS-2.0G PAMAM-IDA. The synthesized resins were characterized by FTIR and elemental analysis. The effect of solution pH, kinetic studies, resin loading capacity, matrix effects etc., on metal ion adsorption to adsorbent phase, were studied by batch method. The PS-1.0G PAMAM-IDA resin was the most excellent adsorbents, with a maximum adsorption capacity of(24.09±1.79) mg/g for Ni2+ ion at pH=7. The interpretation of the equilibrium data was given by Langmuir isotherms model, and the correlation coefficient values for PS-IDA, PS-1.0G PAMAM-IDA and PS-2.0G PAMAM-IDA resins were 0.992, 0.994 and 0.987, respectively.

Optimized Technology for Residuum Processing in the ARGG Unit

引用

China Petroleum Processing & Petrochemical Technology 2006年第2期8卷 25-31页

作者： Pan Luoqi Yuan hongxing Nie Baiqiu Chemical Industry Academy of Sichuan University Chengdu 610065 baling Petrochemical company SINOPEC Yueyang 414014

The influence of feedstock property on operation in the FCC unit was studied to identify the cause leading to deteriorated products distribution related with increasingly heavier feedstock for the ARGG unit. In order to maximize the economic benefits of the ARGG unit a string of measures, including the modification of catalyst formulation, retention of high catalyst activity, application of mixed termina-tion agents to control the reaction temperature and once-through operation, and optimization of catalyst regeneration technique, were adopted to adapt the ARGG unit to processing of the heavy feedstock with its carbon residue equating to 7 % on an average. The heavy oil processing technology has brought about apparent economic benefits.

Simultaneous determination of seven impurities in high-purity cobalt oxide by ICP-AES after matrix separation using 1-nitroso-2-naphthol as a precipitant

Journal of Central South University of Technology 2002年第2期9卷 100-103页

作者：王艳周春山段青兵陈萍 College of Chemistry and Chemical Engineering Central South University Changsha 410083China Quality Inspection Center of Hexanelactam Plant Baling Petrochemical Limited CompanyYueyang 414003 China

A method was developed for the simultaneous determination of seven trace impurities (Cd, Mn, Pb, Zn, Cu, Fe and Ni) in high purity cobalt oxide by ICP AES. The matrix effect was eliminated by preci pitation with 1 nitroso 2 naphthol. The matrix effect of cobalt on the absorptions of trace impurities, the effects of reaction time, pH value, dosage of precipitant on the formation of cobalt 1 nitroso 2 naphthol complex, the effects of hydrochloric acid on the stability of this complex and masking of elements were studied. Recoveries of the impurities in spiked sample are from 90% to 110% with a precision of 1.1% 5.0% RSD. The detection limits of the seven elements are in the range of 0.01 0.24μg/g. The method can be applied to the analysis of high purity cobalt metal, cobalt oxide and other cobalt compounds.
