Heating rate is the speed of heating the reactor to achieve the desired temperature.
To study the influence of the heating rate, the pyrolysis process was conducted at several different heating rates(10, 20, and 50oC/minute) at a temperature of 550oC and nitrogen flow of 3L/minute.
The increase of the heating rate affects to the production of pyrolysis products in which increase the percentage yield of bio-oil and gas, whereas decrease in the char yield
obtained as seen in Figure 2b.
