The GCV of China coal is predicted using 1400 data points in this paper. The support vector machine (SVM) is used to determine the progress of the estimating process, and the estimating robustness is assessed. The SVM model outperformed the three existing models in terms of accuracy and robustness, according to the comparative research.

Chemical Engineering Journal 354 (2018) 2134 29 juli 2018. DME provides advantages in the valorization of feed streams of low H2/CO ratio, which are formed from feedstocks such as biomass or coal. It is currently accepted that the conversion of oxygenates, such as DME or methanol, to hydrocarbons proceeds via the dualcycle mechanism.

The essence of GCV is a concentrated expression of moisture, volatile matter, ash, fixed carbon and other elements. The moisture evaporates in coal combustion, which consumes calories. The ash can affect GCV, which reduces the proportion of combustible portion. There are nonlinear relationship between GCV and mineral composition of coal [35 ...

As a result, good GCV prediction is one of the essential techniques to boost heating value and coal output. This system aims to estimate the GCV of the coal samples from proximate and ultimate parameters of coal using machine learning regression algorithm: the Multiple Linear Regression (MLR) and Local Polynomial Regression (LPR).
