High Calorific Value Fuel from Pyrolysis of Waste De-Oiled Seed Cakes

摘要

The focus of this paper is to produce high calorific value fuel from mahua and neem de-oiled seed cakes. The proximate and ultimate analysis reveal that the high volatile matter, less sulphur and ash content makes it suitable for producing high calorific fuel. TGA analysis reveals that the operating pyrolysis temperature range is 160-530°C. The maximum yield of bio-oil was 42.6 and 38.6%, at the temperature of 450°C and 500°C, whereas the maximum biochar yield was 40.1% and 43.8% at the temperature of 350°C for mahua and neem de-oiled seed cakes respectively, with the heating rate of 20°C/min. The biochar which is made of mainly carbon also finds many applications in industries, agriculture, etc. The chemical properties of bio-oil were similar to the other bio-oils. The bio-oils find many applications due to its advantages of storage, transportation, etc.
