YieldReaction ConditionsOperation in experiment
With water;HUSY (Si/Al=15); at 250℃; under 5250.53 Torr; for 2h;Inert atmosphere;Product distribution / selectivity; In an autoclave (batch reactor) lignin (0.5 g), HUSY (Si/Al=15) (0.5 g) and mixture of water and organic solvent (30 g) were charged. After flushing the reactor with nitrogen gas for 3 times, nitrogen (7 bar) was charged. Reactor was heated up to 230° C. under the stirring (100 rpm). After attaining the desired temperature of 230° C. stirring was increased up to 500 rpm. Reaction was stopped after 30 minutes. Analysis of reaction mixture was done by GC, GC-MS. The lignin used in these examples were organosolv or dealkaline.Yield: >25percentMass balance: >90percent.The effect of reaction temperature and reaction time on depolymerization reaction is demonstrated by the results presented in Table 8 using SiO2-Al2O3 as catalyst*.
