    "The extension of the 100,000-ton/year syngas-to-ethanol industrial demonstration project has been running smoothly for two months since the entire process was opened on January 11.
    The purity of the absolute ethanol produced was as high as 99.
    71%, which marked the world’s first set of coal.
    After the successful commissioning of the dimethyl ether carbonylation to ethanol industrial demonstration project, China has taken the lead in the design and construction of a large-scale industrial plant for mega-ton coal-based ethanol
    .
    " At a press conference held in Beijing on March 17, the Chinese Academy of Sciences Said Liu Zhongmin, an academician and deputy director of the Dalian Institute of Physics
    .
    ?? The project adopts the technology construction jointly developed by Dalian Institute of Chemical Physics, Chinese Academy of Sciences and Shaanxi Yanchang Petroleum Group with independent intellectual property rights
    .
    Yanchang Petroleum chief engineer Hu Guangfa believes that the technology has three practical significance: it can transform a large number of excess methanol plants into ethanol plants, adjust the industrial structure, and release production capacity; ethanol is easy to transport and store, and can partially replace ethylene to produce downstream chemicals.
    , To promote the development of the downstream fine chemical industry; the technology can also produce ethanol from natural gas as a raw material, boosting the implementation of the "One Belt One Road" strategy in countries with rich natural gas resources along the route
    .
    ?? For a long time, the use of fossil resources to produce ethanol has been the goal of the world's efforts
    .
    Based on China's coal-based energy structure, it is urgent to develop complete sets of coal-based fuel ethanol technologies with independent intellectual property rights
    .
    The direct production of ethanol from coal via synthesis gas is a worldwide challenge.
    It has been stuck in the research and development stage due to the difficulty of avoiding the problems of precious metal catalysts, low efficiency and equipment corrosion
    .
    The Dalian Institute of Chemical Industry proposed a process route to synthesize ethanol with coal-based synthesis gas as raw material, carbonylation and hydrogenation of methanol and dimethyl ether
    .
    This route uses non-precious metal catalysts to directly produce anhydrous ethanol.
    It is a unique environmentally friendly new technical route.
    Its core is the carbonylation reaction of dimethyl ether on a molecular sieve catalyst
    .
    Dalian Institute of Chemical Industry has successfully developed a molecular sieve carbonylation catalyst with high activity and high stability, and has made a major breakthrough in the research of dimethyl ether carbonylation, laying the foundation for its industrialization
    .
    ?? In 2012, Dalian Institute of Chemical Technology and Yanchang Petroleum began to jointly carry out the research and development of the entire process technology of syngas to ethanol
    .
    In order to promote the technology to industrial applications as soon as possible, in 2014, Dalian Institute of Chemical Technology and Yanchang Petroleum launched a 100,000-ton/year syngas-to-ethanol industrial demonstration project.
    The installation was under construction in October 2016, and the installation linkage started in December 2016.
    The trial run, on January 11, 2017, produced a qualified absolute ethanol product with a purity of 99.
    71%, and the main indicators reached or exceeded the design value
    .
    The demonstration project can provide design basis and construction and operation experience for the design of mega-ton large-scale industrial ethanol plants
    .
    It is reported that Yanchang Petroleum Group has completed the feasibility study of the 500,000-ton industrial plant of this technology and has started the design and development of the process package
