The XYA-5 catalyst was first applied in commercial scale on an 80-kt/a acrylonitrile unit at the Daqing Refining and Chemical Company. Test results had shown that the once-through yield of acrylonitrile exceeded 80% with the unit consumption ofpropylene reaching 1032 kg on each ton of acrylonitrile. The product quality could be easily put under control and the distribution of reaction products was reasonable with good cleaning performance and stability of the catalyst that was suitable for use on this commercial unit.  相似文献

Over the past decades SINOPEC has been uninterruptedly engaging in the development and upgrading of deep catalytic cracking (DCC) technology for manufacturing propylene from heavy oil. Recently SINOPEC after having made a lot of progress in the area of oil refining at the molecular level has developed a new generation DMMC-1 type catalyst designed for the DCC process. The laboratory evaluation tests have shown that compared to the existing MMC-2 type catalyst that features the best comprehensive performance, the DMMC-1 type catalyst has increased the propylene yield by 2.2% with the propylene selectivity increased by 10%. The said catalyst has improved its ability for heavy oil cracking and coke selectivity along with reduction of olefin content in gasoline to achieve a better product distribution and improve the product quality. The results of application of the said catalyst in a 650-kt/a commercial DCC unit at SINOPEC Anqing Branch Company have revealed that the DMMC- 1 catalyst demonstrated an enhanced capability for heavy oil cracking and could increase the total liquid yield to 84.56 m% from 83.92 m%, the LPG yield to 38.90 m % from 34.60 m %, the propylene yield to 17.80 m% from 15.37 m% and the propylene concentration to 45.91 m% from 44.91 m%, and reduce the coke yield from 7.61 m% to 7.05 m% and the olefin content in gasoline from 42.3 v% to 37.5 v%, resulting in an incremental profit amounting to 52.19 million RMB a year. This technology has further upgraded and developed the DCC technology which has been commanding a leading position among the industry peers.  相似文献

This project adopts the ethylene oligomerization process for manufacture of hexane-1 in the presence of chromium catalyst. The investment in this project totals 74 million RMB and the project is scheduled for completion by the end of September 2008.  相似文献

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.  相似文献

Abstract: The increasingly higher requirement for environmental protection has accelerated the ever upgrading of diesel oil standard. The oil refining industry over the world has continually made improvements and innovations to the existing processes and developed some advanced technologies to meet the requirement for the production of clean diesel oil. This paper summarized the technical progress of diesel oil hydrotreating catalyst in overseas oil refineries. Keywords: clean diesel oil; hydrotreating catalyst; technical progress  相似文献

A new process named CPP (Catalytic Pyrolysis Process) for producing ethylene and propylene from heavy oil feedstock has been developed. The catalyst CEP was specially designed for this process, which has bi-functional catalytic activities for both carbonium ion reaction and free radical reaction, so as to maximize the yields of ethylene and propylene. The commercial trial showed that the yield of ethylene and propylene was 20.37% and 18.23% respectively in maximum ethylene operation with Daqing AR as feedstock, and the yield of ethylene and propylene was 9.77% and 24.60% respectively in maximum propylene operation by using the same feedstock.Compared with steam cracker, the feed cost of CPP is much lower for producing ethylene and propylene.  相似文献

Based on the reaction mechanism of resid hydrodemetallization, a new catalyst carrier was designed and prepared. As compared with the similar type of catalyst carrier, the said new carrier featured a higher pore volume, a larger pore diameter and a weaker surface acidity, which could improve the diffusion performance and stable reaction performance of the catalyst. The active metal components were loaded on the said carrier by a new technique for better metal dispersion, thus the impurity removal rate of the new catalyst, RDM-3, was improved significantly. The commercial test of the RDM-3 catalyst showed that the process of catalyst preparation was stable, the catalyst performance was slightly better than the catalyst prepared in the lab, therefore, the catalyst could be manufactured in commercial scale.  相似文献

The research and development of the CGP-2 catalyst, which was used in the MIP-CGP process for reducing the olefin and sulfur contents of FCC naphtha and enhancing the propylene yield, were introduced. A specific type of metal compound was added into the matrix to provide active centers for reactions including catalytic conversion and selective adsorption of sulfur containing compounds. The CGP-2 catalyst possessed excellent hydrothermal stability to meet the requirements of the 2rid reaction zone of the MIP-CGP process. The commercial test of the said catalyst at the SINOPEC Cangzhou refinery showed that in comparison with the base case (using the CGP-1Z catalyst) the CGP-2 catalyst could reduce the sulfur content of FCC naphtha by 30.32% and increase the propylene yield along with good coke selectivity. Thus, the naphtha produced by the MIP-CGP process at the Cangzhou refinery can meet the new gasoline standard enforced in July 2005.  相似文献
