Abstract

The object of this study is a porous material obtained from the main pollutants of the environment based on intershale clay and oil production wastes without using natural conventional materials. Combustion processes occurring when firing ceramic materials are of great importance, since they mainly determine the operational properties of products. Interest in the chemistry and mechanism of carbon combustion in a porous filler is primarily associated with the use of claydite–concrete wall panels, which in Russia have become the basis for popular industrial construction. Porous filler has been obtained based on production wastes and intershale clay without using natural conventional materials. Combustion processes that take place during the firing of the filler have been studied. The studied oil production wastes have an increased calorific value; therefore, they are advisable to be also used as burnable additives for the production of porous filler. It has been shown that heat treatment of the porous filler in the temperature range of 400–600°C removes most of the volatile substances from the product. In the temperature range of 1050–1100°C, iron reduction is significantly accelerated. At a firing temperature of 1100°C, organic compounds are almost absent in the fired ceramic material.

基于采油废物和页岩间黏土的多孔填料烧成过程中的氧化过程

摘要

本研究的目的是在不使用天然常规材料的情况下，根据页岩间粘土和石油生产废料，从环境的主要污染物中获得一种多孔材料。烧制陶瓷材料时发生的燃烧过程非常重要，因为它们主要决定产品的运行性能。对多孔填料中碳燃烧的化学和机理的兴趣主要与使用黏土-混凝土墙板有关，在俄罗斯，这已成为受欢迎的工业建筑的基础。基于生产废料和页岩粘土，已经获得了多孔填料，而没有使用天然的常规材料。已经研究了填料烧制过程中发生的燃烧过程。研究的石油生产废料的热值增加了；因此，建议将它们还用作生产多孔填料的可燃添加剂。结果表明，在400-600°C的温度范围内对多孔填料进行热处理可以去除产品中的大部分挥发性物质。在1050–1100°C的温度范围内，铁的还原明显加快。在1100℃的烧成温度下，烧成的陶瓷材料中几乎不存在有机化合物。
