The study presents findings from an extensive analysis of coal dust sourced the raw Kulan deposits in Kazakhstan.Various research methodologies including X-ray fluorescence analysis, chromatographic NMR spectral thermogravimetric and IR spectroscopy were employed.Thermogravimetric (TGA DTA) was utilized to explore influence dispersion temperature on mass loss, while granulometric sieving revealed heterogeneous nature sample, with particle sizes ranging 80-160 µm for technical analysis.It observed that particles smaller than 100 constituted over 50% total sample mass, indicating potential variability results depending specific fractions present.High-temperature pyrolysis studies conducted examine effect process, revealing behavior composition.Fine-dispersed displayed heightened sensitivity during thermal decomposition, suggesting additional liquid solid petroleum product extraction through high-temperature pyrolysis.

Not only its abundant resources, but also low rank coal (LRC) can be transformed into different valuable chemical products via syngas. This review focuses on technology of microwave-assisted pyrolysis (MAP) applied LRC as a promising technique thermochemical conversion that transform high quality A confined number reviews has been selected and evaluated to observe current status challenges the technology, including essential production factors, pretreatment LRC, heating characteristics MAP. Experimental research catalytic non-catalytic focusing product distribution resulting from conventional (CP) are discussed. The best yields char, tar, syngas CP at 900 °C were 2%, 41%, 58%, respectively. Meanwhile, oil MAP 620 32%, 15% 53%, Finally, this evaluates advantages milestones achieved in near future.
