The article discusses turning hemp into activated carbon through pyrolysis and gasification. By heating hemp fibers at different rates and temperatures, researchers found that increasing the heating rate decreases char yield but increases gas and oil yield. Increasing the final pyrolysis temperature also affects the yields, with higher temperatures leading to less gas and more oil production. The process resulted in a significant increase in char surface area, from 3 m2/g to over 600 m2/g after activation.
