Formed Coking Through The Copreheattreatment With Additive

使用A240和氢化A240下高温短接触时间条件下的非可靠和略微可靠的煤炭的协同预热方法在500 ° C左右进行了测试，以生产一种形式的可乐，并具有更好的各种发展。这些条件缩短了copheat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treat-treatment时间，并在carbonization后提供了更好的异源性发展，从而在结果可卡因化后提供了更好的异源性发展。短接触时间的有效性已被测试用于各种形态开发的糖分子的依赖性的临界点的有效性，这与类似条件下的煤液体有关。Weathered bituminous coals的碳化特性与那些非Weathered coals进行了比较。“天气减少了煤炭的可行性，以便留下更多的基本异源性行为，并减少了结果可口可乐中异源性行为的最大程度的大小。开发了更多的域和流域文本，在另一边。用一种矿物沥青添加剂进行的共碳化已发现有效地增强了可口可乐中煤炭和其他异构发展的可行性。由潮湿的煤炭制成的配方咖啡是指与添加剂、提供单一尺寸的不同、密集和强烈的可乐的同义词。对于潮湿的煤炭来说，最佳的热处理方法比使用非潮湿的煤炭要短，这表明潮湿的煤炭的高咖啡反应性。来自补充剂的可转移的氢被含有氧气的有毒物质的群体迅速消费。

The co-preheattreatment of non-fusible and slightly fusible coals with A240 and hydrogenated A240 under high temperature-short contact-time conditions around 500 ゜C has been examined in an attempt to produce a formed coke with better anisotropic development. These conditions shortened the copreheat-treatment time and provided better anisotropic development in the resultant coke after carbonization. Effectiveness of short contact-time has been examined interms of the extent of depolymerization of coal molecules suitable for anisotropic development, this being related to coal liquefaction under similar conditions.The carbonization properties of weathered bituminous coals were compared with those of the non-weathered coals. The weathering decreased the fusibility of the coal to leave more basic anisotropy and to diminish the size of the majority of the anisotropy in the resulting coke. On the other hand, more domain and flow domain textures developed. Co-carbonization with a petroleum pitch additive was found effective enhancing the fusibility of the coal and anisotropic development in the coke. Formed coking of the weathered coal by means of copreheat-treatment with the additive, provided an anisotropic, dense and strong coke of uniform size. For the weathered coal, the optimum copreheat-treat-ment was shorter than that using the non-weathered coal, indicating high coking reactivity of the weathered coal. The transferable hydrogens from the additive are rapidly consumed by the oxygen containing groups of the weathered coal.
