Differences between low-temperature pyrolysis and blast furnace coking

Low-temperature coal pyrolysis involves breaking down coal at temperatures of around 500–600 degrees Celsius in an oxygen-free environment, thereby producing chemical products such as semi-coke, gas, and tar. Blast furnace coking is a process in which coal is pyrolyzed at temperatures above 1000 degrees under air-free conditions to produce metallurgical coke, gas, tar, and other chemical products. Apart from the difference in temperature which leads to different coke products, are there also differences in furnace type, tar composition and post-treatment, as well as gas composition and post-treatment?
