Pyrolysis processing of waste peanuts crisps

Abstract

Wastes are the most frequent "by-product" of human society. The Czech Republic still has a considerable room for energy reduction and material intensiveness of production in connection with the application of scientific and technical expertise in the context of innovation cycles. Pyrolysis waste treatment is a promising alternative to the production of renewable hydrogen as a clean fuel. It can also reduce the environmental burden and the amount of waste in the environment at the same time. This paper presents the laboratory pyrolysis experiments of peanuts crisps waste to the final temperature of 800 °C. After the pyrolysis process of the selected waste a mass balance of the resulting products, off-line analysis of the pyrolysis gas and evaluation of solid and liquid products were carried out. The highest concentration of measured hydrogen (66 vol. %) was analysed during the 4^th gas sampling at the temperature varying from 750 to 800 °C.
