The first solution was then heated at 50 ° C. to 60 ° C. until the first solution completely dissolved. Thereafter, a dispersant and water were added to the first solution, and at this time, a second solution was formed while stirring at 40 rpm to 50 rpm for 40 minutes to 50 minutes. Thereafter, the second solution and the mixed fuel (coconut charcoal) were mixed and left to cure at 10 ° C. to 20 ° C. for 20 to 30 minutes to prepare a solid alcohol fuel.
