Understanding the effects of varying pyrolysis conditions on yield and composition of products from oil shales is important for process optimization. The principal objective of this study was to investigate how heating rate, final heat treatment temperature and holding time at final temperature affect the yield and composition of pyrolysis products. A full range of analyses had been run in order to characterize oil shale samples and identify effects of process conditions. A preliminary computed tomography (CT) scan analysis had been peformed for the first time in the literature and kerogen in...
