“…Moreover, the facts also reflected the effect of desulfurization temperature on SO 2 profiles. The results in this study might improve the previous observation [10][11][12][13][15][16], even Ca content in shellfish adsorbent is much lower than those in scallop shell and limestone adsorbents.…”

“…During the past two decades, there have been a number of studies to improve the quality of coal briquettes by various method such as carbonizing the coal before briquetting [1][2] or adding lime-based adsorbent (CaO) into coal briquettes [3][4][5][6][7][8][9][10][11][12][13][14][15][16]. An industrial briquette produced from mixture of hard coal, molasses pulp and hydration limestone gives an effective SO 2 reduction in a 46.5 MW traveling grate furnace [4].…”

Combustion of coal and co-combustion of their co-fuel contribute to gas emissions. Among the gas emissions are SO x , NO x , CO and CO 2 . Introduction of calcium based adsorbent is addressed to absorb SO 2 that release to the atmosphere during the combustion process. Objective of the research is at first to observe the physical characteristics of biobriquettes as a function of briquette compositions (coal to palm kernel shell ratios) and Ca/S ratios (Ca in adsorbent and S in briquette) using a natural adsorbent (shellfish waste). The second objective is to investigate desulfurization characteristics as a function of Ca/S ratios and desulfurization temperatures at coal to palm kernel shell ratio of 90:10 (wt %). Ratios of coal to palm kernel shell in this study are 90:10, 80:20, 70:30, 60:40 and 50:50; and Ca/S ratios are 1:1, 1.25:1, 1.5:1, 1.75:1 and 2:1. Binding agent used is the mixture of Jatropha curcas seeds and starch as much as 10% (wt). It was found that introducing the palm kernel shell and adsorbents in the coal briquette affect the water resistant and compressive strength. The highest water resistance and compressive strength were 5,165 second and 34 kg/cm 2 , respectively. The lowest SO 2 level found in this study was 1 ppm for all Ca/S ratios, except for 1:1.

“…Calcium-based materials added in coal for F retention were mainly used in industrial technology such as fluidized bed and industrial chain furnace [29]. Little attention is paid on the environmental effect of the briquettes mixed with calcium-based materials in open ovens in coal-burning fluorosis area of southwestern China [30][31][32]. Most retention materials used in previous studies are chemical substances, which need more pure CaO, and have limit for CaCO 3 and other minerals, but the materials we used have no limit for these minerals.…”

In this study, a lignite sample from Afşin‐Elbistan area of Turkey was briquetted using rice husk as additive. The lignite and the rice husk were first briquetted separately without blending under pressures of 280, 555, 830, and 1110 MPa. Lignite–rice husk blends were prepared to contain 2, 5, 10, and 20 wt % rice husk as additive. The blends were also briquetted using three different binder materials (molasses, starch, and black liquor). Shatter index, compressive strength, and water resistance of the formed briquettes were determined and compared. Addition of rice husk into Afşin‐Elbistan lignite caused to decrease the water resistance, but improved the mechanical strength of the briquettes. Using binder materials affected both compressive strength and shatter index negatively. But the water resistance of the briquettes increased with increasing binder material concentration. Adding rice husk changed the combustion characteristics of Afşin‐Elbistan lignite considerably and shifted its burning profile to lower temperatures. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 742–748, 2017
