WebNov 3, 2024 · Eight coal characteristics (including pyrolysis temperature, proximate and ultimate analyses) were chosen as input parameters. Multiple linear regression (MLR), support vector machine (SVM), and random forest (RF) were applied as base model to form the fusion model (FU). WebIn this work, an experimental device was designed to analyze the dynamic characteristics of the tar release process at different temperatures. The tar yield was continuously recorded during the process of coal pyrolysis; then the release proportion of coal tar, which was similar to weightless conversion in thermogravimetric analysis, was defined. lahore takeaway stoke on trent
