The influence of structural order of anthracite fillers on the curing behavior,morphology, and dynamic mechanical thermal properties of epoxy composites

This article concerns the study of polymer composites with anthracite fillers of various structural order. Raw Svierdlovski anthracite of turbostratic structure and the anthracite thermally treated at 2,000°C of graphite‐like structure were used as fillers of low‐molecular‐weight diglycidyl ether of bisphenol A cross‐linked with aliphatic amine. Two anthracites of extremely different structures were compared to natural graphite that is composed of well‐ordered graphene sheets. Systematic studies of the influence of the structure of anthracite filler on the curing behavior, morphology, dynamic mechanical thermal properties, and thermal stability of epoxy composite were performed. It was found that the structure of anthracite filler affects the cross‐linking reactions of the epoxy matrix as well as the morphology of the composites and their viscoelastic properties. Raw anthracite added to epoxy matrix had a visible effect on the activation energy and differential scanning calorimeter parameters of the curing process, in contrast to the epoxy matrix modified with anthracite heated at 2,000°C. On the contrary, the effect of anthracite on dynamic mechanical behavior of composites is more evident when the anthracite prepared at 2,000°C was used as a filler. POLYM.

Industrial use of low-phosphorus anthracite in the production of high-carbon ferrochrome

The use of anthracite in the production of high-carbon ferrochrome is assessed. The theoretical and technological aspects of electrothermal production of high-carbon ferrochrome are analyzed. The physicochemical characteristics of anthracite and coke nuts are compared. It is established that the ash content of anthracite is low. More importantly, its content of phosphorus and sulfur is very low. An advantage of anthracite is its high electrical resistance. The use of anthracite in the production of high-carbon ferrochrome in 21-MV A furnaces reduces the consumption of reducing agent (by 1.9%) and electric power (by 6.8%). The extraction of chromium is practically unchanged. The production costs (per 1 t of high-carbon ferrochrome) are reduced. The use of anthracite in more powerful furnaces (63 MV A) permits significant increase in the working voltage and decrease in power consumption by 2.0–2.5%. The phosphorus content in the ferrochrome is reduced with increase in anthracite content in the batch.     

High temperature air-blown gasification of Korean anthracite and plastic waste mixture

Korean anthracite is too high in ash contents and low in calorific value to be used as an industrial energy source, the demand for anthracite has rapidly decreased and its competitiveness weakened. To overcome the problem, a mixture of Korean anthracite and plastic wastes low in ash and high in calorific value was manufactured. A 1.0T/D fixed bed gasification process was developed to understand the gasification characteristics of the mixtures and secure operation technology using Korean and Chinese anthracite. For the Korean anthracite, the syngas composition and heating value are varied from 10 to 20% and from 300 to 800 kcal/Nm³ as a function of steam/air/fuel ratio. Therefore, it is concluded that Korean anthracite is hard to gasify because of low reactivity. For the Chinese anthracite low ash content and higher heating value than domestic anthracite, the syngas composition was maintained at about 20–40% and the calorific value was 800–1,300 kcal/Nm³. A reformer using high-temperature air/steam was installed just after the gasifier to combust and convert tar and soot into syngas. We confirmed that the amount of generated tar and soot showed a salient difference after running the reformer. In the future, gasification experiments of manufactured mixtures of anthracite and plastic waste using 1.0T/D fixed bed gasifier will be performed. This work was presented at the 6 ^th Korea-China Workshop on Clean Energy Technology held at Busan, Korea, July 4–7, 2006.
