Summary

This paper investigates oxygen extraction from lunar regolith via chemical reduction using thermogravimetric analysis (TGA). It compares pure ilmenite and the highland-type simulant NU-LHT-2M under hydrogen, methane, and pure nitrogen. Results show ilmenite is a good reference for hydrogen reduction, while methane reduction is complicated by carbon deposition and side reactions.

The text also contains some fragmented or incomplete sentences, possibly due to formatting issues or data extraction errors. The provided text is a detailed scientific report focusing on thermogravimetric analysis (TGA) of two materials: ilmenite and NU-LHT-2M. The study investigates the weight changes of these materials under different gas atmospheres (nitrogen, hydrogen, methane) and includes microscopic analysis of the samples before and after reduction. The report also i
