Abstract
Reports results of investigation of transformations of high-molecular-mass heteroatomic compounds, such as resins and asphaltenes, present in atmospheric distillation residue of crude oil from the Usa field in the Republic of Komi by thermal cracking at temperatures of 350–450°C in the presence of fly ash ferrospheres as initiator additives.
The structural group parameters of resin and asphaltene molecules existing in the feedstock and the thermolysis products were determined using elemental analysis, molecular mass, and proton NMR data.
