“…Conversions of methane to value-added chemicals provide commercially profitable paths for sustainable utilization of high concentrated methane. The use of flare gas as a feedstock to produce syngas and subsequent liquid fuels through Fischer–Tropsch (F–T) synthesis has been investigated and can recover at least 20% of unburnt methane . However, such technologies still face challenges such as necessary methane purification, large storage facility footprints, and additional power consumption.…”

With 28−34 times the greenhouse effect of CO 2 over a 100-year period, methane is regarded as the second largest contributor to global warming. Reducing methane emissions is a necessary measure to limit global warming to below 1.5 °C. Photocatalytic conversion of methane is a promising approach to alleviate the atmospheric methane concentrations due to its low energy consumption and environmentally friendly characteristics. Meanwhile, this conversion process can produce valuable chemicals and liquid fuels such as CH 3 OH, CH 3 CH 2 OH, C 2 H 6 , and C 2 H 4 , cutting down the dependence of chemical production on crude oil. However, the development of photocatalysts with a high methane conversion efficiency and product selectivity remains challenging. In this review, we overview recent advances in semiconductor-based photocatalysts for methane conversion and present catalyst design strategies, including morphology control, heteroatom doping, facet engineering, and cocatalysts modification. To gain a comprehensive understanding of photocatalytic methane conversion, the conversion pathways and mechanisms in these systems are analyzed in detail. Moreover, the role of electron scavengers in methane conversion performance is briefly discussed. Subsequently, we summarize the anthropogenic methane emission scenarios on earth and discuss the application potential of photocatalytic methane conversion. Finally, challenges and future directions for photocatalytic methane conversion are presented.

“…At present, the most important and large-scale problem in reducing the anthropogenic emission of hydrocarbon gases is the cessation of APG flaring at numerous small producing fields both on land and offshore platforms. In this regard, various possibilities of APG use and processing are analyzed [5,6]. Among possible methods for gas transformation are gas to hydrate (GTH), gas to liquid (GTL), gas to wire (electricity) through combined heat and power (CHP) systems, compressed natural gas (CNG), liquefied petroleum gas (LPG) recovery, and liquefied natural gas (LNG) [5].…”

Other possibilities, such as compression and reinjection of gas into oil wells to enhance oil production, NGL refinery, fuel production, production of chemicals, for example, methanol and dimethyl ether (DME), and power generation are also considered [6].…”

“…Note, however, that the problem is complicated by the fact that the vast majority of natural and anthropogenic sources of hydrocarbon gases have a low flow rate, a factor that makes their accumulation, transportation or processing by existing largescale industrial methods unprofitable. This is the main reason for the ongoing flaring of APG [5,6], the global volume of which, despite all the efforts made, has not been reduced in the last decade, remaining at the level of ~140 billion m 3 /yr (Fig. 1).…”

A variety of natural and anthropogenic sources of hydrocarbon gases make a significant contribution to the global emission of greenhouse gases. Reducing the anthropogenic emission of industrial hydrocarbon gases is impossible without new technologies that would allow their cost-effective utilization. The paper describes a number of new promising technologies based on autothermal gas-phase processes of partial oxidation and oxidative cracking of various hydrocarbons, such as associated petroleum gases, coalbed methane, refinery gases, and biogas, which open up prospects for a significant reduction in their flaring or emission into the atmosphere. Among the technologies under consideration are those involving their processing for subsequent use in the energy sector and low-tonnage production of various demanded chemicals.
