Molecular sieve manufacturer talks about microporous and mesoporous molecular sieves that can convert natural gas into fuels and chemicals

The known global reserves of natural gas are sufficient to meet demand for over a century, indicating that the era of oil has passed. Methane (natural gas) is a very promising fuel source and value-added platform for chemicals. Its high C/H ratio and low impurity atom (0, N, S) content make it attractive as a raw material for producing clean fuels. The raw materials for producing chemicals need to be functionalized. Due to the fact that most of the abundant natural gas is located in remote areas, far from densely populated user markets, converting natural gas into a transportable form on site is the most convenient way to make money from these natural gas resources. Activating methane is very difficult because it has a stable and symmetrical molecular structure. Its C-H bonding energy is 425kJ/mol, and its catalytic reaction usually requires technical support and less cost. Below, the editor of the molecular sieve manufacturer will explain the two main methods of catalytic conversion of methane into fuel and chemicals.
The direct route is to convert methane in one step. In the indirect route, the carbon in methane is first "stored" in a more active molecular state, such as CO, and then "released" during the synthesis of natural gas or synthetic gas (CO+H2), participating in a wider range of transformations.
In the direct conversion route, methane is directly converted into products with higher relative molecular weight and lower C/H through an oxygen free pathway. The synthesis process releases hydrogen gas, which is a valuable byproduct. However, in the anaerobic pathway, unfavorable thermodynamics hinders each route from achieving high yields. In order to improve conversion rate, it is necessary to continuously and selectively remove at least one product (usually H2). Dehydrogenation and aromatization of methane and non oxidative coupling of methane are the main oxygen free direct conversion routes. As an alternative, the direct oxidation route utilizes external oxidants to provide a driving force by continuously consuming hydrogen through the generation of water, in order to avoid thermodynamic limitations. However, in this case, kinetic factors also limit the achievement of the highest yield, as methane is typically converted into heat-resistant products. However, the C-H binding force is weak, so when the reaction is carried out at a high conversion rate, it is easier to completely oxidize to C0X. In this case, to avoid kinetic limitations, "chemical protection" or selective removal of the generated product from the reaction intermediate is also necessary. Methane oxidative coupling, methane oxidative fixed alkylation, and methane partial oxidation are all included in these direct oxidation conversion routes. Generally speaking, the direct route is a requirement for energy conservation and cost-effectiveness, although there are currently no economic benefits. In order to increase the yield of each route, a feasible improvement is to use complex technologies to achieve interest rates due to large-scale production at the current level of development. Hunan Providence New Materials Co., Ltd is a professional molecular sieve manufacturer which can provide USY zeolite, NaY zeolite, REY zeolite, ZSM-5 zeolite, welcome to consult.
