Abstract  

First casein was processed by pyrolysis and investigated under optimal thermal treatment condition to obtain a good quality adsorbent with high developed porosity structure and liquid product as a complex raw material for different kind of organic compounds with interesting properties and structures. The yields of hard residue, pitch, pyrolysis water and gases were determined and compared with the yields of pyrolysis products of other investigated different kind of organic materials. The chemical composition of pitch was determined as following: free carbons - 4.52%, organic acids - 0.64%, organic bases -38.00%, phenols - 7.75%, asphaltenes - 0.97%, paraffin's - 1.30%, neutral oils - 16.20% and preasphaltanes - 30.10%. The pitch was fractionated by air distillation into 3 liquid fractions with different boiling range and a bitumen like residue with a lower softening temperature.
