Catalytic Dehydrogenation of Ethane: A Mini Review of Recent Advances and Perspective of Chemical Looping Technology

Abstract: Dehydrogenation processes play an important role in the petrochemical industry. High selectivity towards olefins is usually hindered by numerous side reactions in a conventional cracking/pyrolysis technology. Herein, we show recent studies devoted to selective ethylene production via oxidative and non-oxidative reactions. This review summarizes the progress that has been achieved with ethane conversion in terms of the process effectivity. Briefly, steam cracking, catalytic dehydrogenation, oxidative dehydrogen… Show more

“…This finding was also observed in other literature [29]. It should be noted that the reaction temperature of ethane dehydrogenation is commonly high and a broad temperature range (300-1000 • C) based on the selected production process including steam cracking process (above than 1000 • C), catalytic dehydrogenation (550-700 • C), and oxidative dehydrogenation (350-600 • C) [35,36]. To confirm the adaptability of resultant MMHFM in this application, its thermal stability was examined by TGA analysis.…”

“…The utilization of tandem reactions such as the one-pot production of cyclic carbonates starting directly from biobased unsaturated fatty acids esters [8], the one-pot production of ethylene carbonate from ethylene produced by low-energy-demanding methods [2,108] or the production of HMEC from chlorinated bio-based glycerol [109] seems to be very promising for effective CO 2 fixation.…”

“…During the isothermal period, the gas atmosphere was altered by switching the gas to pure N 2 (125 mL min −1 ) or air (125 mL min −1 ). The measured OSC m of the OC was calculated using Equation (6), where m air is the weight of the OC at equilibrium in air and m N2 is the weight of the OC at equilibrium after changing the atmosphere to N 2 The reducibility of the OC materials was investigated isothermally at 500 °C by changing the between air, N 2 and 6% C 2 H 6 /N 2 . In addition, TPR experiments were carried out by heating up the sample to 600 °C at a rate of 5 °C min −1 .…”

“…[4] Globally, this results in the emission of more than 300 million tons of CO 2 per year by the steam cracking of ethane alone. [5] Alternative, potentially environmentally more friendly production technologies for ethylene, for example, the catalytic dehydrogenation of ethane or the oxidative coupling of methane, [6][7][8] are currently not economically competitive with steam cracking, but they may become more important in the near future due to i) an increase of carbon taxes and other carbon pricing initiatives, ii) the increasing global ethylene demand, and iii) the growing production of shale gas, in particular in the U.S., providing a relatively inexpensive source of ethane. [2,6,9] Our work is concerned with the catalytic oxidative dehydrogenation of ethane (ODH), a reaction route to ethylene whereby conventionally ethane and oxygen are cofed (Equation (2), Figure 1a).…”
