Coal hydrogenolysis in the presence of NaOH

High pressure hydrogenolysis of coal was carried out in the presence of sodium hydroxide at 350–500 °C and initial pressures of 3, 10 and 13 MPa for 15–60 min. Similar experiments were carried out under nitrogen. The yield of solid product decreased with increased reaction temperature because of the...

Summary:High pressure hydrogenolysis of coal was carried out in the presence of sodium hydroxide at 350–500 °C and initial pressures of 3, 10 and 13 MPa for 15–60 min. Similar experiments were carried out under nitrogen. The yield of solid product decreased with increased reaction temperature because of the increased production of gases which are mainly hydrocarbons. Extraction of the solid products, formed under hydrogen, with pyridine and benzene shows higher yields than when nitrogen is used. This indicates that depolymerization and hydrogenation reactions were accelerated in the presence of sodium hydroxide under hydrogen.
