“…China specified in 2005 that the concentration of formaldehyde in class 1 civil buildings must be less than 0.08 mg/m³. Therefore, the improvement of indoor air quality must receive extensive attention [ 3 ]. Among many methods, nano-Ti O2 photocatalytic technology has been widely concerned because of its unique advantages, but the visible light utilization rate is low due to the defects of nano-Ti O2 itself, so it is necessary to modify nano-Ti O2 to improve the visible light utilization rate and photocatalytic performance, as shown in Figure 1 .…”

In order to understand and improve the degradation rate of formaldehyde, the study on the chemical structure and thermal properties of nano-titanium dioxide resin by free formaldehyde was proposed. In this research, nano-titanium dioxide was prepared by the low temperature hydrolysis method and characterized by using the scanning electron microscope (SEM) and X-ray diffraction (XRD). The degradation behavior of formaldehyde was studied by using the degradation rate of formaldehyde in the container as the evaluation index. The influence of the photocatalytic coating on the degradation rate of formaldehyde under different loading conditions, different temperatures, and different humidity was investigated. The experimental results show that the formaldehyde degradation rate of the photocatalytic coating prepared by loading 5 g nano-TiO2 into a 200 g emulsion system can reach 93% under the conditions of room temperature of 25°C, humidity of 50%, and UV lamp irradiation of 120 min. Conclusion. This study is obviously better than the commercial P25 nano-titanium dioxide degradation effect of formaldehyde.

“…These results are in accordance with literature reports, in which analogous results at higher temperatures for different liquid and polysiloxane‐based solid catalysts were reported. [ 20 ] Another important aspect is the formation of methyl formate as a side product. The content of methyl formate is considerably increasing with temperatures above 60 °C and reached a maximum value of ≈12 wt% at 100 °C.…”

Polyoxymethylene dimethyl ethers (OMEn) are considered as substituents or additives for fossil diesel fuel. Efficiency of the synthesis is crucial for the development of industrial scale production plants. Therefore, the design of suitable catalysts and the efficient heating play important roles in OME fuel synthesis. In this work, microwave‐assisted synthesis (MAS) is carried out and compared to a classical approach using standard thermal heating. Different polymeric materials, e.g., Amerlyst15, are utilized as catalysts, and screened for the catalytic synthesis of OME. Within this approach, the kinetics of the reaction are analyzed in detail.

“…For instance, the cetane number of OME 3 to OME 5 is in the range of 72-93 (Lautenschütz et al, 2016;Deutsch et al, 2017) and the flash, boiling and melting points are comparable to those of diesel fuel (Zheng et al, 2013;Omari et al, 2019). These suitable characteristics explain the recent research interest in this specific group of oxygenated fuels in the field of kinetic mechanism development (Sun et al, 2017;He et al, 2018;Cai et al, 2019;Li et al, 2020;Bai et al, 2021;Niu et al, 2021), their application in engine simulations (Lin et al, 2019;Lv et al, 2019;Ren et al, 2019) or for different synthesis methods (Gierlich et al, 2020;Klokic et al, 2020), and the assessment of the overall carbon impact (Mahbub et al, 2019;Bokinge et al, 2020). The application of oxymethylene ethers in engines in combination with their emission propensity has been investigated in several studies (Pellegrini et al, 2013;Barro et al, 2018;Huang et al, 2018;Liu et al, 2019;Ren et al, 2019;LeBlanc et al, 2020;Parravicini et al, 2020;Pélerin et al, 2020), while fewer investigations have been conducted, notably, into soot formation for pure or blended OMEs in canonical flames (Ferraro et al, 2021;Tan et al, 2021).…”

Synthetic fuels, especially oxygenated fuels, which can be used as blending components, make it possible to modify the emission properties of conventional fossil fuels. Among oxygenated fuels, one promising candidate is oxymethylene ether-3 (OME3). In this work, the sooting propensity of ethylene (C2H4) blended with OME3 is numerically investigated on a series of laminar burner-stabilized premixed flames with increasing amounts of OME3, from pure ethylene to pure OME3. The numerical analysis is performed using the Conditional Quadrature Method of Moments combined with a detailed physico-chemical soot model. Two different equivalence ratios corresponding to a lightly and a highly sooting flame condition have been investigated. The study examines how different blending ratios of the two fuels affect soot particle formation and a correlation between OME3 blending ratio and corresponding soot reduction is established. The soot precursor species in the gas-phase are analyzed along with the soot volume fraction of small nanoparticles and large aggregates. Furthermore, the influence of the OME3 blending on the particle size distribution is studied applying the entropy maximization concept. The effect of increasing amounts of OME3 is found to be different for soot nanoparticles and larger aggregates. While OME3 blending significantly reduces the amount of larger aggregates, only large amounts of OME3, close to pure OME3, lead to a considerable suppression of nanoparticles formed throughout the flame. A linear correlation is identified between the OME3 content in the fuel and the reduction in the soot volume fraction of larger aggregates, while smaller blending ratios may lead to an increased number of nanoparticles for some positions in the flame for the richer flame condition.
