Research progress in low-temperature carbonization technology for low-rank coal with efficient tar recovery
摘要
Abstract
As the core for clean,high-efficient and scientific grading utilization of low-rank coal, low-temperature carbonization technology has attracted great attention. However , there are considerable disadvantages in the industrial application of existing coal low-temperature carbonization technology,such as low tar recovery rate and high requirement for raw material size. Development of low-temperature carbonization technology with efficient recovery of tar has become the focus of low-rank coal utilization. The typical low-temperature carbonization technologies of coal worldwide were compared and discussed in terms of structural characteristics of carbonization furnace,raw materials,carbonization products,energy utilization and tar recovery rate. The major characteristics of tar efficient recovery technology in low-temperature carbonization developed by author’s group were presented. Analysis shows that the development aims of low-temperature carbonization technology include scaling-up,developing automatic and efficient environment-friendly technology of carbonization furnace,improving heat recovery and utilization of high-temperature semi-coke and coke-oven gas, achieving multipurpose utilization of pulverized coal,finding coke dry quenching technology,and investigating the grading conversion technology for the fast,catalytic carbonization in low temperature.关键词
