Embodiment 1
[0059] Embodiment one: (VO 2 ) 2 SO 4 Preparation of sulfuric acid solution
[0060] Take one liter of sulfuric acid with a concentration of 5wt% and heat it to 50°C; add 0.1mol of V 2 o 5 , stirred for 5h, filtered to obtain (VO 2 ) 2 SO 4 sulfuric acid solution.
Embodiment 2
[0061] Example 2: Preparation of Modified Methanol Fuel
[0062] Take one liter of sulfuric acid with a concentration of 7.5wt% and heat it to 60°C; add 0.5mol of V 2 o 5 , stirred for 5h, filtered to obtain (VO 2 ) 2 SO 4 sulfuric acid solution.
[0063] Cool to room temperature and add 1 liter of methanol aqueous solution of 50wt%, mix homogeneously and make (VO 2 ) 2 SO 4 Convert to (VO)SO 4 , to obtain the cocatalyst containing (VO)SO 4 modified methanol fuel.
Embodiment 3
[0064] Example 3: Preparation of High Concentration Modified Methanol Fuel
[0065] Take one liter of sulfuric acid with a concentration of 10wt% and heat it to 70°C; add 1mol of V 2 o 5 , stirred for 5h, filtered to obtain (VO 2 ) 2 SO 4 sulfuric acid solution.
[0066] Cool to room temperature and add 4 liters of methanol aqueous solution of 60wt%, mix homogeneously and make (VO 2 ) 2 SO 4 Convert to (VO)SO 4 , to obtain a high concentration of co-catalyst containing (VO)SO 4 modified methanol fuel.
