Example 4.9 Solar-grade silicon can be manufactured by thermal decomposition of silane at moder- ate pressure in a fluidized-bed reactor, in which the overall reaction is: SiH4(g) → Si(s) + 2H2(g) When pure silane is preheated to 300°C, and heat is added to the reactor to promote a reasonable reaction rate, 80% of the silane is converted to silicon and the products leave the reactor at 750°C. How much heat must be added to the reactor for each kilogram of silicon produced?
