Coal Seam Roof and Floor Lithology Prediction for Underground Coal Gasification Based on Deep Residual Shrinkage Network

Energy Science &Engineering, Volume 13, Issue 3, Page 1361-1374, March 2025.
This study proposes the deep residual shrinkage network (DRSN), a model combining advanced strategies for rapid and accurate lithology prediction. It enables efficient lithology evaluation in early underground coal gasification. ABSTRACT Lithology identification is a crucial task in coal underground gasification projects, serving as a prerequisite for ...

Artificial neural network based modelling approach for municipal solid waste gasification in a fluidized bed reactor [PDF]

Waste Management (Elsevier), Volume 58, December 2016, Pages 202-213, 2018
In this paper, multi-layer feed forward neural networks are used to predict the lower heating value of gas (LHV), lower heating value of gasification products including tars and entrained char (LHVp) and syngas yield during gasification of municipal solid waste (MSW) during gasification in a fluidized bed reactor. These artificial neural networks (ANNs)

Designing of Underground Coal Gasification Unit

Journal of Advanced Research in Fluid Mechanics and Thermal Sciences, 2020
Pakistan is one of the biggest country for coal reserves in the world. Those coal reserves if exploited, will help in fulfilling the growing need of Pakistan’s energy sector. The ultimate goal for “Underground Coal Gasification” is to design a new system that can produce sufficient electricity and is relatively cleaner and environment-friendly.

Potential U.S. Production of Liquid Hydrocarbons From Biomass With Addition of Massive External Heat and Hydrogen Inputs

GCB Bioenergy, Volume 17, Issue 2, February 2025.
This study examines the future potential of the U.S. to convert biomass into liquid hydrocarbons, leveraging external low‐carbon heat and hydrogen to prioritise biomass foremost as a carbon feedstock. Using three market scenarios from the 2023 Billion‐Ton Report and two augmented cases, we estimate a mature‐market production potential ranging from 4791
