For a given temperature, conversion fraction was found by dividing the mass loss by the total mass loss at the end of the process.
It can be defined as equationwhere, t is time, x is the conversion fraction, n is thereaction order and k is the rate constant.
It was observed that the apparent activation energy of coal combustion varied with the
conversion fraction. The high CaO lignite was found to show higher activation energy than the low CaO coal.
Remember: To make your
conversion fraction, put the number of days in the previous year's month on the bottom, and the number of days in your planning year's month on top.
The epoxy
conversion fraction, denoted x, at the time t was calculated from [Delta][H.sub.t] and [Delta][H.sub.0], the total reaction heat at the initial time (t = 0):
