“…The solid deposit on the electrodes is also analyzed using IR spectroscopy and electron microscopy. A review on the plasma-chemical production of acetylene from hydrocarbons in Russia is given by Bilera et al, 60 and a state of the art of the industrial applications of plasma for the production of petrochemicals and hydrogen is discussed by Slovetskii. 61 Beiers et al 62 studied the pyrolysis of hydrocarbons in a hydrogen plasma at atmospheric pressure and temperatures in the range 1000−2000 °C.…”

The cracking of hydrocarbons is a highly energyintensive process with large CO 2 emissions. Industrial steam crackers use gas-fired furnaces, which produce a global CO 2 emission of about 366 Mt/year. Modern crackers have been improved through the years to increase performance and reduce greenhouse emissions. However, the improvements are limited, and the required future CO 2 emission reductions cannot be achieved with the present designs. Electrification is a promising option to make cracking processes more sustainable, especially if renewable electricity is used. Electric heating will result in energy savings as flue gas losses are avoided, while CO 2 emissions will be reduced radically if renewable electricity is used. This paper evaluates the current state of electric cracking and identifies potential electric heating technologies for the electrification of cracking processes. Various electric heating technologies are reviewed, an extensive literature search is conducted on their application in cracking processes, and industrial applications of electric cracking are compiled. The study shows that resistance (Ohmic) heating is a promising electric heating technology for steam cracking of naphtha. The technology is relatively easy to scale up and can be used to retrofit existing crackers. The cost of electric cracking is expected to be higher than conventional cracking, mainly due to the current electricity price being higher than the gas price. However, the cost of naphtha represents about 80% of the ethylene production cost, so possible selectivity improvements could reduce the overall cost through lower feedstock consumption. The electrification of the cracking processes can be stimulated by guaranteeing sufficient availability of renewable electricity and by introducing a CO 2 tax.

“…Other drawbacks, such as severe reaction conditions and necessity of handling and feeding solids, also led to the replacement of most coal-to-acetylene processes by alternative routes, such as partial oxidation of methane and pyrolysis of hydrocarbons (e.g., methane, ethane and propane) by heating or in electric arc. [3] Depending on the feedstock and reaction conditions, the product streams contain only certain percentage of C 2 H 2 and the commonly seen gaseous co-products include ethylene (C 2 H 4 ), carbon dioxide (CO 2 ), carbon monoxide (CO) and hydrogen (H 2 ). The C 2 H 2 can be obtained as a separate product by absorption from the gas stream using organic solvents (e.g., N-methylpyrrolidone or dimethylformamide) or through the highly energy-intensive cryogenic distillation processes, and the crude C 2 H 2 also contains various impurities, such as ammonia (NH 3 ), hydrogen sulfide (H 2 S), hydrogen cyanide (HCN), phosphine, arsine and etc, which are usually removed by scrubbing and other gas clean-up operations.…”

“…Although this historic method opened the route to large‐scale production and extensive applications of C 2 H 2 in the 20 th century, the process is energy‐intensive and relies on the use of coal or coal‐derived coke. Other drawbacks, such as severe reaction conditions and necessity of handling and feeding solids, also led to the replacement of most coal‐to‐acetylene processes by alternative routes, such as partial oxidation of methane and pyrolysis of hydrocarbons (e.g., methane, ethane and propane) by heating or in electric arc [3] …”

Since its first industrial production in 1890s, acetylene has played a vital role in manufacturing a wide spectrum of materials. Although current methods and infrastructures for various segments of acetylene industries are wellestablished, with emerging functional porous materials that enabled desired selectivity toward target molecules, it is of timely interest to develop new efficient technologies to promote safer acetylene processes with a higher energy efficiency and lower carbon footprint. In this Minireview, we, from the perspective of materials chemistry, review state-of-the-art examples of advanced porous materials, namely metal-organic frameworks and decorated zeolites, that have been applied to the purification and storage of acetylene. We also discuss the challenges on the roadmap of translational research in the development of new solid sorbent-based separation technologies and highlight areas which require future research efforts.

“…Одним из таких способов может оказаться пиролиз метана в плазме (плазмолиз) [1][2][3][4]. Ранее плазмолиз метана при помощи дуговых плазмотронов рассматривался как способ получения ацетилена, демонстрировалась высокая степень конверсии [5,6]. Кроме того, плазмолиз метана рассматривался как способ получения углеродных нанопорошков и углеродных нанотрубок [7,8].…”

The possibility of converting methane into hydrogen using a high-frequency induction plasma torch at atmospheric pressure has been experimentally studied. The dependencies of the degree of methane conversion and the rate of hydrogen production were studied depending on the process conditions. It has been demonstrated that the degree of conversion of methane to hydrogen can reach values close to 100%.
