“…The methodology of calculating the rate of heat release (RoHR) from the measured pressure could be found in Section 3.1 of Ref. [5]. Exhaust gaseous emissions were measured using an AVL CEBII pollutant analyzer, while soot emissions (evaluated by absorption coefficient (AC)) were measured using an AVL 439 Opacimeter.…”

“…Engine combustion studies using PODE as a diesel fuel additive have been conducted. Diesel blends with 10-20% PODE by volume [5] in a direct injection diesel engine can significant reduce carbon monoxide (CO), hydrocarbon (HC) and particulate matter (PM) emissions and slightly increase thermal efficiency. With the application of EGR, NOx emissions are also very low.…”

“…Methylal then reacts with paraformaldehyde forming PODE components. The desired PODE components to be blended with diesel are PODE [3][4][5] and the ratio of the three components can be changed by adjusting reaction conditions. Unconverted methylal and undesired short-chain PODE 2 compound are fed back to the reactor.…”

“…The absence of C-C bonds in OMEs is the decisive element, allowing a combustion with decreased soot formation. [10][11][12][13][14][15] Excitingly, previous engine studies already emphasized the significant potential of OMEs as fuel additives for reducing soot and NO x emissions. More specifically, an addition of 35 vol % of OMEs to standard diesel fuel reduces the soot formation by 90 %.…”

One example are oxymethylene ethers (OME x ) of different chain lengths, which are intended to be used as diesel blends. Especially OME 3-5 show properties comparable to diesel. The key to producing longer chain OMEs is OME 1 as feedstock, which can react with formaldehyde to afford larger molecules. This article reviews different synthesis routes for OME 1 , in order to elucidate energy-efficient methods.

“…Therefore, it is an important factor for methanol chemical process that the catalysts exhibit good hydrothermal stability and appropriate adsorption capacity for hydrophilic and hydrophobic materials. [7][8][9][10][11][12][13][14][15][16] Liu and coworkers 15 studied combustion and emission performance of PODE diesel blends in light-and heavyduty diesel engines. [2][3][4] Polyoxymethylene dimethyl ethers (PODE) with the formula CH 3 O-(CH 2 O) n -CH 3 (n ≥ 2) are a kind of ether without carbon-carbon bonds.…”

Summary Polyoxymethylene dimethyl ethers (PODE) are excellent promising diesel oil additives or replacements because of the special structure without carbon‐carbon bond. A novel solid dichlorodiphenylsilane‐modified ZrO2–γ‐Al2O3 catalyst with both hydrophobic and hydrophilic sites exhibited good catalytic activity and desired product selectivity for the reaction of methanol and formaldehyde aqueous solution to PODE. A single type of active center (only hydrophobic center or hydrophilic center) did not perform well for the PODE synthesize reaction from methanol and formaldehyde because of the different hydrophobic properties of methanol, formaldehyde, methylal, and PODE. The experimental results confirmed that the hydrophobic sites and hydrophilic sites of the catalyst surface promote the synthesis of PODE and methylal, respectively. The enhancement of the hydrophobic property of the catalyst surface promotes the production of long chain PODE. Further study indicated that the product distribution can be controlled artificially by adjusting the content of hydrophobic agent, and the desired polymerization degree of PODE can be optimally synthesized by a modified catalyst (called HYB‐26.9@ZrO2–γ‐Al2O3). Reaction temperature and pressure were also investigated for the PODE synthesis reaction with this modified catalyst, HYB‐26.9@ZrO2–γ‐Al2O3. Low reaction temperature benefits the synthesis of long chain PODE because of the limit of reaction equilibrium. The stability of the catalyst was proven by a 240‐hour running test.
