Patent number: 10544242Abstract: The invention discloses a process for preparing high-performance propylene polymers, the process utilizing a high activity, highly stereoselective Ziegler-Natta catalyst and two or more stages of polymerization carried out under different hydrogen concentrations to prepare propylene polymers having broad molecular weight distribution, wherein non-uniformness of isotacticity of molecular chains of the final propylene polymers is improved by adjusting or controlling stereoselectivity of catalytic active sites under different hydrogen concentrations, namely, making the low molecular weight fraction of the polymers having a higher isotacticity and making the high molecular weight fraction of the polymers having a lower isotacticity, thereby overcoming the drawbacks of the propylene polymers having broad molecular weight distribution known in the art. The resulting final polymers have excellent combined properties, in particular, remarkably improved mechanical properties.Type: GrantFiled: May 12, 2015Date of Patent: January 28, 2020Assignees: China Petroleum & Chemical Corporation and Beijing Research Institute of Chemical Industry, China Petroleum & Chemical CorporationInventors: Wenbo Song, Meifang Guo, Jinliang Qiao, Zhichao Yang, Shijun Zhang, Luqiang Yu

Patent number: 9181419Abstract: A toughened plastic and its preparation method, with the toughened plastic being obtained by rubber-plastic blending of brittle or less brittle plastics and a rubber mixture. The rubber mixture consists of powdery rubbers having a cross-linked structure and an average particle size of not more than 0.50 ?m, and at least one selected from the group consisting of unvulcanized rubbers and thermoplastic elastomers. The morphology and the particle size distribution of the rubber phase contained in the toughened plastic can be controlled by changing the particle size of the powdery rubbers having a cross-linking structure and choosing proper unvulcanized rubbers or thermoplastic elastomers. The toughened plastic has good toughness and processability while keeping better strength and stiffness.Type: GrantFiled: November 5, 2001Date of Patent: November 10, 2015Assignees: CHINA PETROLEUM AND CHEMICAL CORPORATION, CHINA PETROLEUM AND CHEMICAL CORPORATION BEIJING RESEARCH INSTITUTE OF CHEMICAL INDUSTRYInventors: Jinliang Qiao, Yigun Liu, Shijun Zhang, Xiaohong Zhang, Jianming Gao, Wei Zhang, Genshuan Wei, Jingbo Shao, Hua Yin, Renli Zhai, Zhihai Song, Fan Huang

Publication number: 20120219466Abstract: The invention relates to an ethylene cracking furnace having a multi-pass radiant coil, comprising at least one radiant section. In the radiant section there are provided with bottom burners and/or sidewall burners, and at least one set of multi-pass radiant coil longitudinally arranged in the radiant section. The multi-pass radiant coil is a four- to ten-pass type radiant coil. At least one tube of the multi-pass radiant coil is arranged to be spatially adjacent to a tube which is not consecutive to said at least one tube. With this arrangement, the thermal radiation influence between tubes with high temperature can be reduced, so that the tubes with low temperature can absorb the radiation heat from the tubes with high temperature. Therefore, the surface temperature of the tubes with high temperature can be reduced, thus extending the lifetime of the radiant coil and the operational cycle of the cracking furnace.Type: ApplicationFiled: October 26, 2010Publication date: August 30, 2012Applicants: China Petroleum & Chemical Corporation, China Petroleum & Chemical Corporation Beijing Research Institute of Chemical Industry, SINOPEC Engineering IncorporationInventors: Xiou He, Changli li, Zhaobin Zhang, Jingkun Liu, Mujun Yuan, Cong Zhou, Yuping Guo, Yonghua Zhao, Hainu Shen

Publication number: 20020065378Abstract: The present invention relates to a silica gel-supported catalyst component suitable for ethylene (co)polymerization, a catalyst therefrom and use of the same. The catalyst component according to the present invention is obtained by supporting the reaction product of a titanium compound, a halide promoter, a magnesium compound and an electron donor on silica gel having a larger specific surface area. When the resultant catalyst is used for ethylene polymerization, especially gas phase fluidized bed polymerization, not only the activity is substantially enhanced, but also the hydrogen response, copolymerizability of ethylene with other alpha-olefins, and the like are improved. The catalyst is especially suitable for the fluidized bed polymerization operated in a condensed state, with high quality LLDPE resins being obtained.Type: ApplicationFiled: August 22, 2001Publication date: May 30, 2002Applicant: CHINA PETROLEUM & CHEMICAL CORPORATION AND BEIJING RESEARCH INSTITUTE OF CHEMICAL INDUSTRYInventors: Hekuan Luo, Ruiguo Tang, Kejing Gao, Qinfang Zhao, Jingyan An, Hua Yang, Jinsheng Huo
