Abstract Within the so-called bioliq® process, renewable carbon resources, especially agricultural residues, are converted to gasoline. The process chain comprises pyrolysis of the feedstocks, gasification to synthesis gas, gas cleaning and conversion of synthesis gas to dimethyl ether (DME) followed by conversion of DME to hydrocarbons. Construction of all process units has been completed now and the entire plant has been successfully operated in several campaigns. Thus, hundreds of liters of a new alternative gasoline are available now, which allow for an extensive testing. The basic characteristics of the resulting bioliq®/100 fuel are described. It is rich in aromatics and a blend consisting of 90 Vol.−% of conventional RON95 E5 fuel and 10 Vol.−% of bioliq®/100, designated as bioliq®/10, has been produced which meets the DIN EN 228 standard. Initial measurements on a single cylinder research engine have been carried out focusing on efficiency and emissions. A comparison of bioliq®/10 with neat RON95 E5 revealed an improved knocking behavior of bioliq®/10 even by a small fraction of regenerative bioliq® fuel. Particle as well as hydrocarbon emissions from bioliq®/10 are significantly higher than in the case of RON95 E5. Increased particle emissions are attributed to the higher content of aromatics. Soot reactivity has been investigated and soot from bioliq®/10 exhibits higher reactivity than soot from RON95 E5.

来自 bioliq® 工艺的汽油：生产、表征和性能

摘要 在所谓的 bioliq® 工艺中，可再生碳资源，尤其是农业残留物，被转化为汽油。工艺链包括原料的热解、气化为合成气、气体净化和合成气转化为二甲醚 (DME)，然后 DME 转化为碳氢化合物。目前所有工艺单元的建设已经完成，整个工厂已经成功运行了几次。因此，现在有数百升新的替代汽油可供使用，从而可以进行广泛的测试。描述了所得 bioliq®/100 燃料的基本特性。它富含芳烃，生产了一种由 90 Vol.−% 的常规 RON95 E5 燃料和 10 Vol.−% 的 bioliq®/100 组成的混合物，指定为 bioliq®/10，符合 DIN EN 228 标准。已经对单缸研究发动机进行了初步测量，重点是效率和排放。bioliq®/10 与纯 RON95 E5 的比较表明，即使使用一小部分可再生 bioliq® 燃料，bioliq®/10 的爆震行为也有所改善。bioliq®/10 的颗粒和碳氢化合物排放量明显高于 RON95 E5。增加的颗粒排放归因于较高的芳烃含量。已经研究了烟尘反应性，并且来自 bioliq®/10 的烟尘表现出比来自 RON95 E5 的烟尘更高的反应性。bioliq®/10 的颗粒和碳氢化合物排放量明显高于 RON95 E5。增加的颗粒排放归因于较高的芳烃含量。已经研究了烟尘反应性，并且来自 bioliq®/10 的烟尘表现出比来自 RON95 E5 的烟尘更高的反应性。bioliq®/10 的颗粒和碳氢化合物排放量明显高于 RON95 E5。增加的颗粒排放归因于较高的芳烃含量。已经研究了烟尘反应性，并且来自 bioliq®/10 的烟尘表现出比来自 RON95 E5 的烟尘更高的反应性。
