Recently, Sun Jian and Ge Qingjie, team members of the Dalian Research Institute of Chemical Physics, Chinese Academy of Sciences, have successfully implemented CO2 direct addition by designing a new type of Na-Fe3O4/HZSM-5 multifunctional composite catalyst. Hydrogen produces high-octane gasoline. Relevant research results were published in Nature Communications (DOI: 10.1038/ncomms15174) and were reviewed by reviewers as "a breakthrough in the field of catalytic CO2 conversion."
The large consumption of fossil energy has led to a dramatic increase in the emission of greenhouse gases such as CO2, which has caused increasingly severe environmental problems such as global warming. Gasoline is one of the most used fuels in the world. If CO2 is used as raw material to produce gasoline, it will be a potential alternative to fossil fuel clean energy strategy. It can not only effectively reduce the greenhouse effect caused by CO2, but also reduce dependence on traditional fossil fuels. . However, the activation and selective conversion of CO2 still face enormous challenges.
The research team has long been dedicated to the catalytic conversion of syngas and CO2 in small molecules of carbon resources (Fuel, 2011, 90, 2051-2054; Fuel, 2014, 134, 11-16; Catal. Sci. Technol., 2016, 6 , 4786-4793), has accumulated rich experience in the design of multifunctional catalysts. In this work, the research team designed a highly efficient and stable Na-Fe3O4/HZSM-5 multi-functional composite catalyst. Under conditions close to industrial production, the catalyst achieved low selectivity of CH4 and CO, and gasoline in hydrocarbon products. The selectivity of distillate hydrocarbons (C5-C11) reaches 78%. Gasoline fractions are mainly high-octane iso-paraffins and aromatics that basically meet the requirements of the National V Standard for the composition of benzene, aromatics and olefins. The catalyst also has good stability and can be continuously operated for more than 1000 hours. The study of the reaction pathways for the direct conversion of CO2 to gasoline shows that the precise regulation of the multi-active site structure and its proximity effect is the key to realizing CO2 hydrogenation to gasoline. This technology not only expands new ideas for the research of CO2 hydrogenation to liquid fuels, but also provides new ways for the use of intermittent renewable energy (wind, solar, water, etc.).
The above research work was funded by the National Natural Science Foundation of China and the “100-person planâ€.
Cabinet integral handle - Introduction to cabinet integral handle
The overall handle of the cabinet refers to the appliances (such as
circular handle rope, rope and handle) that pull or operate (open, close
and hang). The handle is a component installed on the door body to
facilitate door opening and closing. The handle in the industrial box
has many forms and functions, and the quality is better than that of the
ordinary handle. Wooden strips or metal objects installed on cabinets
or drawers for easy opening and closing by hand.
Cabinet integral handle - Introduction to the classification types of cabinet integral handle
According to materials, there are: zinc alloy handle, copper handle,
iron handle, aluminum handle,aluminium profile handle,aluminium
handle,handle aluminium kitchen set,handle kitchen set
aluminium,aluminium profile handle kitchen, bakelite handle, log handle,
ceramic handle, plastic handle, crystal handle, stainless steel handle,
acrylic handle, marble handle, Aluminium Handle for cabinet,pull handles for aluminium door,aluminium finger pull,aluminium gate handle,aluminium glass door handleetc.
By material: single metal, alloy, plastic, ceramic, glass, etc;
According to the shape: tubular, strip, spherical and various geometric shapes;
By style: single strip type, double head type, exposed type, closed type, etc;
By style: avant-garde, leisure and nostalgic (such as rope or hanging bead);
By use: handle for home decoration, industrial handle, handle for luggage cabinet.
Cabinet integral handle - precautions for cabinet integral handle
When selecting the handle, we must pay attention to the style, function
and place of the furniture. Generally speaking, there are two handling
principles for the relationship between the handle and the furniture,
either eye-catching or hidden. For the furniture with the main use
function, the handle should be recessive, so as not to hinder the use of
the owner. The handle of the food decoration cabinet can adapt to its
own eye-catching style, and choose the double headed handle with luster
and contrast with the color of the furniture.
