“…Therefore, it would be highly desirable if flue gas mixtures (typically 8-10% CO 2 , 18-20% H 2 O, 2-3% O 2 and 60-70% N 2 ) could be used directly for CO 2 conversion without costly pre-separation of CO 2 . Song and colleagues (Song 2000(Song , 2001Song & Pan 2004) have pioneered a novel process centred on the unique advantages of directly utilising flue gas, rather than pre-separated and purified CO 2 from flue gases, for the production of hydrogen-rich syngas from methane reforming of CO 2 (so-called 'dry reforming'). The overall process, named 'tri-reforming', couples the processes of CH 4 /CO 2 reforming, steam reforming of CH 4 , and partial oxidation and complete oxidation of CH 4 .…”

“…In terms of catalyst materials, the majority of studies have focused on the important CH 4 -CO 2 reforming component of the tri-reforming process (Song & Pan 2004;Song 2006;Cho et al 2009). Both nanoparticulate Ni and Co have frequently been employed as active metal components owing to their high intrinsic catalytic activities, wide availability and (relatively) low costs (Hu 2009).…”

Our present dependence on fossil fuels means that, as our demand for energy inevitably increases, so do emissions of greenhouse gases, most notably carbon dioxide (CO 2 ). To avoid the obvious consequences on climate change, the concentration of such greenhouse gases in the atmosphere must be stabilized. But, as populations grow and economies develop, future demands now ensure that energy will be one of the defining issues of this century. This unique set of (coupled) challenges also means that science and engineering have a unique opportunity-and a burgeoning challenge-to apply their understanding to provide sustainable energy solutions. Integrated carbon capture and subsequent sequestration is generally advanced as the most promising option to tackle greenhouse gases in the short to medium term. Here, we provide a brief overview of an alternative mid-to long-term option, namely, the capture and conversion of CO 2 , to produce sustainable, synthetic hydrocarbon or carbonaceous fuels, most notably for transportation purposes.Basically, the approach centres on the concept of the large-scale re-use of CO 2 released by human activity to produce synthetic fuels, and how this challenging approach could assume an important role in tackling the issue of global CO 2 emissions. We highlight three possible strategies involving CO 2 conversion by physico-chemical approaches: sustainable (or renewable) synthetic methanol, syngas production derived from flue gases from coal-, gas-or oil-fired electric power stations, and photochemical production of synthetic fuels. The use of CO 2 to synthesize commodity chemicals is covered elsewhere (Arakawa et al. 2001 Chem. Rev. 101, 953-996); this review is focused on the possibilities for the conversion of CO 2 to fuels. Although these three prototypical areas differ in their ultimate applications, the underpinning thermodynamic considerations centre on the conversionand hence the utilization-of CO 2 . Here, we hope to illustrate that advances in the science and engineering of materials are critical for these new energy technologies, and specific examples are given for all three examples.With sufficient advances, and institutional and political support, such scientific and technological innovations could help to regulate/stabilize the CO 2 levels in the atmosphere and thereby extend the use of fossil-fuel-derived feedstocks.

“…The production of syngas is a potential area for large-scale CO 2 conversion and utilization. The reforming of CO 2 to CH 4 has been extensively studied and reported on in the literature (Song & Pan, 2004). The catalytic reduction of CO 2 to form methanol (or even CH 4 ) using renewable energy sources could become a viable alternative to scarce or expensive fossil resources.…”

“…Herewith, SG is generated in the composition of mixed fuel, which is further used directly in engine operating cycle. This type of conversion is referred to as tri-reforming [31][32][33][34][35][36]. Since typical composition of EG contains low amount of oxygen (ÑÎ 2 = 9-10 %, Í 2 Î = 18-20 %, Î 2 = 2-3 %, remainder -N 2 ), then the EG heat and heat generated upon oxidation of initial fuel by remaining oxygen can be insufficient for endothermic reaction of steam and carbon dioxide conversion of fuel.…”

This work discusses the issues of thermochemical recovery as a method to improve efficiency of fuel utilization in external heat engines (EHE).Key words: Catalyst, Synthesis gas, Thermochemical recovery, External heat engine, mathematical model.Practical application of thermodynamic cycles of thermal machines is related with implementation of heat transfer from heating source to working fluid (WF) or heat withdrawal from it after working cycle. With regard to thermal engines, conversion of chemical energy of fuel into work is implemented in two stages: at the first stage energy is converted into heat, and at the second stage the obtained heat is converted into work. In this relation intensification of heat transfer is one of the conditions of improvement of the observed efficiency of thermodynamic cycles of thermal machines. Theoretical efficiency of reversible thermodynamic cycle is determined by the ratio of difference between average maximum temperature and average minimum temperature of heat withdrawal and does not exceed the efficiency of the Carnot cycle. Increase in the average maximum temperature is limited with thermal resistance of materials and increase with heat losses of engine into external environment. In this regard selection of WF for EHE is highly important. Decrease in average temperature of heat withdrawal is limited with environmental and engineering considerations. Due to existence of such limitations the only way to increase overall efficiency of engine is related with heat recovery of exhaust gases (EG) by means of TCR either of cogeneration.It 3027-3039 (2015) with EG into environment equals to 35 %; heat transferred to cooling system: 30 %; portion of losses due to incomplete fuel combustion: about 2 %, and unaccounted heat losses reach 3 %. Theoretically, it is possible to recover heat losses related with heat withdrawal into environment and into cooling system, and thus to achieve increase in thermal efficiency. The essence of TCR is that a portion of EG heat and heat, transferred into engine cooling system, is used for endothermic conversion of initial fuel into another type of fuel possessing higher enthalpy of products. Due to this there is an increase in total efficiency of fuel utilization [2][3][4]. In terms of energy the most profitable solution is conversion of fuels into SG, which is a mixture of CO and Í 2 . The first scientific background of this method to improve EHE efficiency was given by Nosach [5], who specified it as TCR, and its practical implementation was applied to stationary solid fuel facilities.The use of TCR makes it possible to achieve two important purposes simultaneously: 1) to increase the lower heating value of reformates with regard to initial fuel. Theoretical maximum increase can reach 20-22 % upon steam reforming of propane to CO and H 2 (without ÑÎ 2 and especially of ÑÍ 4 in the composition) [2]. 2) to increase stability of catalytic burning in nonadiabatic operation mode of catalytic burner (due to heat withdrawal into engine or just heat losse...
