CO sulfur tolerant shift catalyst for the company to declare

   Since its establishment in 2010, the company has been focusing on technological innovation, increasing scientific research investment, and actively encourage technical personnel to study and create new technologies, and achieved fruitful results. In the past few years has been the basis of a number of invention patents, and recently applied for a patent: a CO sulfur tolerant shift catalyst pre curing method, in addition, a number of patents are being reported. The patent relates to my company's main product upgrading upgrading and proprietary technology solutions, to achieve these patents, is my company for many years adhere to the "advance with the times, reform, technology innovation and technology", fully embodies the scientific and technical personnel work.

   Prevulcanizing method for CO sulfur tolerant shift catalyst for our company with independent intellectual property rights and presulfided catalyst technology through the identification of scientific and technological achievements of the relevant departments of the (KTRES), namely, the oxidized catalyst depth after curing, the special treatment of passivation technology. This method solves the present stage oxidation states of sulfur tolerant shift catalyst used before using in-situ presulfurization shortcomings fundamentally: curing time is long, cure is not uniform, the curing degree is low, the curing process is not stable, started a long time, the startup operation is difficult, need to process large amounts of gas. Compared with the conventional oxidation catalyst, the pre curing sulfur tolerant shift catalyst is used without curing, and the pure nitrogen is heated to a predetermined temperature, and the process gas can be directly used. Sulfurization of the catalyst prepared by the method of curing conditions: stability, convenient construction, shorten the starting time of 2/3, the operation more safety, reduce the start process of carbon emissions; sulfur catalyst more fully, greatly improving the utilization ratio of the active component and catalytic activity. Sulfur tolerant shift catalyst storage, transport and loading process without nitrogen protection.

   My company is currently the world's only successful research and development of sulfur tolerant shift catalyst and successful application of the factory, the technology can bring huge economic benefits for the application. To 500 thousand tons / year ammonia plant as an example to calculate the economic efficiency indicators, compared to the process of gas pre curing program, using KTRES pre curing technology, can save more than 8 million yuan of operating costs. To 600 thousand tons / year of methanol synthesis plant as an example, the economic benefit index calculation, compared the process gas sulfide solution and H2+CS2 circulating fluidized scheme, using KTRES pre vulcanization technology, can save operating costs of more than 4 million yuan and 3 million yuan.

   As of August 2016, has been successfully applied in 7 sets of large-scale coal chemical plant, pre vulcanized sulfur tolerant shift catalyst has been subjected to high loads, atmospheric conditions and other harsh process conditions and long period, continuous, stable operation of the test.
