Abstract: REACTIVE FORM COKE, MADE AS DESCRIBED IN WORK ET AL., U.S. PATS. 3,140,241 AND 3,140,242, ISSUED JULY 7, 1964, IS TREATED WITH AN AQUEOUS DISPERSION OF A FILM FORMER TO DEPOSIT ON AND ADJACENT THE SURFACE THEREOF FROM ABOUT 0.05 TO ABOUT 3 WEIGHT PERCENT OF A SOLID WHICH ADHERES TO THE SURFACE AND DEPOSITS IN THE SURFACE PORES, AND ACTS BOTH TO REDUCE ABRASION AND TO CAUSE MATERIAL ABRADED FROM THE SURFACE TO BE LARGER IN SIZE THAN ULTRAFINE (20-MICRON AND SMALLER) PARTICLES WHICH ARE PRODUCED IN THE ABSENCE OF THE COATING, THEREBY CONTROLLING THE AIRBORNE-DUST PROBLEM WHICH OTHERWISE MAKES HANDLING OF THE REACTIVE FORM COKE EXTREMELY DIFFICULT.

Abstract: A novel composite briquette useful in producing iron is made by briquetting a reactive coal calcinate made as described in Work et al. U.S. Pat. Nos. 3,140,241 and 3,140,242, and iron oxide, with a bituminous binder, using proportions to insure at least 50 percent carbon plus hydrogen by weight, then curing the briquettes in the presence of a gas containing at least 5 percent of oxygen at briquette temperature of 450* to 575*F, and then further heating the cured briquettes at 1600* to 1800*F, whereby at least 90 percent of the iron is reduced. The briquette is distinguished by consisting of iron particles embedded and evenly distributed through a uniform solid carbonaceous structure.

Abstract translation: 用于生产铁的新型复合煤饼是通过压块如Work等人所述制备的活性煤煅烧而制成的。 美国专利 编号3,140,​​241和3,140,​​242以及具有沥青粘合剂的氧化铁，其使用比例以确保至少50％的碳加氢重量，然后在含有至少5％的氧的气体的存在下固化团块， 450°F至575°F，然后在1600°至1800°F下进一步加热固化的团块，从而减少至少90％的铁。 煤块的特征在于嵌入的铁颗粒和通过均匀的固体碳质结构均匀分布。
