“…In the case of oxidation stability, the hydroprocessed fuel meets the specification limit, and the reduction achieved by the hydroprocessing is very important, as the value was reduced from 49 to 2.1 g/m 3 . Oxidation stability is related to the presence of olefins in the fuel, which are more prone to oxidation and the formation of insoluble measured by EN ISO 12205 (similar to ASTM D2274) [46,47]. The method that is used in the petroleum industry for the indirect determination of olefins is the bromine number.…”

Abstract:The long term ambition of energy security and solidarity, coupled with the environmental concerns of problematic waste accumulation, is addressed via the proposed waste-to-fuel technology. Plastic waste is converted into automotive diesel fuel via a two-step thermochemical process based on pyrolysis and hydrotreatment. Plastic waste was pyrolyzed in a South East Asia plant rendering pyrolysis oil, which mostly consisted of middle-distillate (naphtha and diesel) hydrocarbons. The diesel fraction (170-370 • C) was fractionated, and its further upgrade was assessed in a hydroprocessing pilot plant at the Centre for Research and Technology Hellas (CERTH) in Greece. The final fuel was evaluated with respect to the diesel fuel quality specifications EN 590, which characterized it as a promising alternative diesel pool component with excellent ignition quality characteristics and low back end volatility.

“…There seems to be a linear relationship between the accelerated storage time and the formation of insoluble residues. In the literature, it is well-known that fossil diesel fuel with and without FAME content is susceptible to oxidation, where a number of radical-chains react with ambient air to gums, insoluble deposits, and acidic compounds. − For example, autoxidation during the primary oxidation phase leads to intermediate products such as peroxides or hydroperoxides. These intermediates continue to react to acids, aldehydes, gums, and sediments within a secondary oxidation phase. , Both diesel samples of week 8 and 24 appear to be different in their aging.…”

While a large part of traffic volume can be electrified to avoid local pollutant emissions, some applications will still require an internal combustion engine as an energy converter in the future. Construction machines such as vibratory plates, excavators, or emergency generators are examples of such applications. In order to reduce or avoid the pollutants of the remaining internal combustion engines, exhaust aftertreatment systems or synthetic fuels can be implemented. One category of these literature-discussed fuels is poly(oxymethylene) dimethyl ether (OME). In this work, neat OME as well as four OME− diesel blends and conventional diesel fuel as reference were investigated according to the material compatibility of two elastomers (NBR and FKM) and long-term storage stability of the fuel itself. The material compatibility of OME according to both elastomers NBR and FKM is difficult. The tensile stress test (DIN 53504), the Shore hardness (ISO 7619-1), and the compression set (ISO 815-1) show significant changes for neat OME compared to the diesel used elastomers. In addition, the change of mass and volume of the elastomers (DIN ISO 1817) are up to 75 wt % and 140 vol % higher compared to diesel fuel. Only FKM specimens, which were submerged in an OME−diesel blend with 5 vol % OME content, show comparable properties to the diesel reference. Based on the findings of this work, it is concluded that engines with NBR or FKM seals should replace their seals with OME resistant seals. In contrast, the long-term storage stability (ASTM D4625-14) of OME has much better properties than diesel fuel. No deposits were detectable after 24 weeks accelerated fuel aging at an ambient temperature of 43 °C.
