“…The reformate mixtures were produced from a CPOX reformation process of diesel fuel. Initially, the fuel was oxidized at various equivalence ratios and pressures to study their effect on the reformate products' concentrations, which were determined using gas chromatography-mass spectrometry [34]. Following that, gas bottles were procured and used for the experimental study with a reformate composition that matched the gas chromatographymass spectrometry-determined results as closely as possible.…”

“…Therefore, an approximation of the species concentrations was made and was validated in a previous study [35]. More details on the reformation process and the reformate's combustion characteristics were presented in earlier studies [34,35]. The molar concentration of both the diesel reformate fuel mixtures, along with their fuel density and lower heating value is shown in Table 2.…”

“…To assess the viability of a diesel's reformate mixture as a lowreactivity fuel in single fuel RCCI, the combustion characteristics of two diesel reformate mixtures were studied in HCCI combustion [34]. The speciation of diesel reformate-1 (DR1) and diesel reformate-2 (DR2), respectively, were found to have a relatively low reactivity-the effective octane numbers of both reformate mixtures studied are higher than gasoline.…”

A new concept of single-fuel RCCI has been proposed through the catalytic partial oxidation reformation of diesel fuel. The reformed fuel mixture is then used as the low reactivity fuel and diesel itself is used as the high reactivity fuel. In this paper, two selected reformates mixture from the reformation of diesel were selected for further analysis. Each reformate fuel mixture contained a significant fraction of inert gases (89% and 81%). The effects of the difference in the molar concentrations of the reformate mixtures were studied by experimenting with diesel as the direct injected fuel in RCCI over a varying start of injection timings and different blend ratios (i.e., the fraction of low and high reactivities fuels). The reformate mixture with the lower inert gas concentration had earlier combustion phasing and shorter combustion duration at any given diesel start of injection timing. The higher reactivity separation between reformate mixture and diesel, compared with gasoline and diesel, causes the combustion phasing of reformate-diesel RCCI to be more sensitive to the start of injection timing. The maximum combustion efficiency was found at a CA50 before TDC, whereas the maximum thermal efficiency occurs at a CA50 after TDC. The range of energy-based blend ratios in which reformate-diesel RCCI is possible is between 25% and 45%, limited by ringing intensity (RI) at the low limit of blend ratios, and COV of IMEP and combustion efficiency at the high limit.

“…According to the literature, the carburization gases CO and H 2 used in this study can be obtained by the reformation of natural gas [30] or from the steel smelting process. In contrast to the traditional BF-BOF long process, the proposed technology uses clean gas as a carburization gas and heat source, and the method does not require sintering, pelletizing, coking, or blast furnace ironmaking processes.…”

The rapid development of the steel industry in China has concurrently led to the rapid consumption and depletion of easily processible iron ores. Thus, considerable attention has been focused on the utilization of refractory iron ores to meet the requirements of the steel industry. [1,2] In this context, sideritecontaining FeCO 3 is an important and typical refractory iron resource, [3] with current deposits in China totaling to nearly 1.83 billion tons. However, the average iron grade of Chinese siderite is 33%, and thus, its direct utilization is difficult. Meanwhile, numerous studies have reported that only %10% of siderite ore is reused as siderite utilization is significantly limited by the low iron grade, fine grain size, and complex mineralogy. [4,5] Currently, most iron ores are used to prepare blast furnace burden. In contrast to easily processible iron ores, low-grade iron ores must first be preprocessed to high-grade iron ore concentrates, particularly in the case of low-grade siderite. In this regard, traditional processing methods such as flotation, magnetic, and gravity separation have been adopted to increase the iron grade. [6][7][8] However, siderite exhibits a fine iron grain size, complex mineralogy, and isomorphism, so it is difficult to improve the iron grade of siderite. In addition, the strength of the blast furnace burden made with siderite cannot meet the blast furnace requirement due to FeCO 3 decomposition and subsequent CO 2 liberation during the siderite roasting process. [9,10] Currently, it has been proven that magnetization roasting followed by magnetic separation is effective for treating siderite. [1,11] With this treatment, FeCO 3 can be transformed into Fe 3 O 4 , which is a high-quality concentrate used for preparing blast furnace burden. Nevertheless, coal is the first choice for magnetization roasting; however, this enhances the production cost and causes environmental pollution owing to coal combustion. [1] After magnetization roasting, the concentrate produced by siderite is used to prepare the blast furnace burden via the traditional blast furnace-basic oxygen furnace (BF-BOF) long process. However, the traditional BF-BOF long process, including coking, pelletizing, sintering, blast furnace ironmaking, and BOF steelmaking, consumes abundant coal and coke, leading to the release of large amounts of oxynitride and carbon dioxide. [12,13] According to the literature, [13][14][15] the traditional BF-BOF long process exhausts %80% CO 2 and 84% NO x in the steel industry. In 2016, China's steel industry contributed to 32% of CO 2 and 10% of NO x emissions. [16] Thus, siderite utilization based on traditional BF-BOF long processes causes serious environmental problems.To efficiently utilize siderite, Zhu et al. developed a technique called direct reduction roasting-magnetic separation. [5] With this treatment, FeCO 3 is transformed into Fe, which can be used as electric arc furnace (EAF) burden. This technique avoids coking, pelletizing, sintering, and blast furnace ironmaking p...
