Physico-chemical foundations of produced syngas during gasification process of various hydrocarbon fuels

The gasification processes of coal, coal–water slurry, and natural bitumen were studied. A new method involving application of hydrocarbon fuels was proposed. It allows one to create process schemes which can be adopted for changing feedstock’s properties in a wide range by the variation of gasification parameters. The integrated gasification unit allows using the local resources and not being dependent on external fuel deliveries. However, for designing such projects, it is necessary to study the physicochemical processes involved in the thermochemical processing of various fuel types. For calculation of gas composition, three fuel types were selected: Kamsky long-flame coal, coal–water slurry based at Kama coal dust, and natural bitumen from Ashalchy oil field. During thermochemical processing of various feedstock types, by varying gasification parameters, syngas with the required application ratio of CO/H₂ was obtained. These fuels have various compositions, but they are located at one region. The syngas thus produced may be used in the chemical and energy industries.
