Oxymethylene ethers (OMEs) are important diesel additives because of their ability to reduce soot loading, particulate matter (PM) emissions, and NOx emissions. Some research has been undertaken on the feasibility of producing OMEs from biomass but there is no techno‐economic assessment of OME production from biomass. In this study, we estimate the unit cost to produce OMEn (n = 1–8) from three different biomass types common to western Canada: whole‐tree woodchips, forest residues, and wheat straw. The techno‐economic model uses the OME production simulation results for 500 MT day−1 of dry biomass. The simulation results show that 97.70, 98.86, and 99.80 MT day−1 of OME1–8 can be produced from whole‐tree woodchips, forest residues, and wheat straw, respectively. The costs of producing OME per liter over 20 years of production are $1.93 ±0.15/L, $1.68 ±0.14/L, and $1.66 ±0.13/L, respectively, at a 95% confidence level for whole‐tree woodchips, forest residues, and wheat straw biomass. The sensitivity analysis results show that the internal rate of return, OME yield, capital cost, and biomass delivery cost significantly influence OME unit price. The production price versus capacity profile reveals that the optimum minimum price can be obtained at a plant capacity of 4000 MT day−1 of biomass; beyond this, the increase in capacity does not result in any appreciable decrease in production price. © 2018 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…An entire process chain from biomass to OMEs has been outlined recently [21,22]. In this context, Zhang et al reported a process design starting from woody biomass [23,24]. If OMEs are produced from renewable resources not only soot and NO x emissions can be reduced, but also overall CO 2 emissions ranging from feedstocks to combustion in terms of a holistic solution.…”

Oligomeric oxymethylene dimethyl ethers (OME n , CH 3 (OCH 2 ) n OCH 3 , n = 1 -5) are promising diesel fuels for the reduction of harmful emissions. If OMEs are produced from dimethoxymethane and trioxane, the resulting OME mixtures usually contain residual trioxane which appears, after rectification, in the OME 2 fraction. To circumvent this obstacle, substoichiometric amounts of trioxane have been employed in OME synthesis. Thus, OME 2 samples with high purity could be prepared. Physicochemical and fuel data of high purity OME 2 and higher OMEs have been determined to supplement previously reported data.

“…For example, oxymethylene ethers (OME), synthesised from formaldehyde and alcohols, are investigated as potential candidates for combustion fuels and fuel additives. [8][9][10] It could be envisioned to extend this approach using long-chain bioderived alcohols, thus resulting in long-chain OMEs suitable to complement biofuels such as biodiesel (Scheme 1). 8 Worth mentioning is also the long established use of solid formaldehyde derivatives as solid fuel tablets for direct combustion commonly used for small camping stoves especially in military equipment since the 1930s.…”
