MoO3-SILICATE SLUDGE CATALYST FOR COAL LIQUEFACTION

Silicate sludge obtained from a geothermal power generation plant was applied to prepare the catalyst for coal liquefaction. The sludge has a very high surface area, a large pore volume, and a wide-range pore size distribution. It was found that the activity of the catalyst prepared by supporting MoO3 on the sludge is superior to commercially available Ni–Mo/Al2O3 catalyst.
