GONZALEZ-ROCHA, J.C.; URQUIZA-BELTRAN, G  e  LONGORIA-RAMIREZ, R. Parametric Study of Gasification of the Mexican Petroleum Coke: Effect Feed Petroleum Coke on Energetic Characteristic of the Synthetic Gas (syngas). Ing. invest. y tecnol. [online]. 2011, vol.12, n.3, pp.291-300. ISSN 2594-0732.

In this work, a parametric study the gasification of the Mexican petroleum coke from the refineries of Cd Madero (CRM) and Cadereyta, Nuevo León (CRC) is performed. It is evaluates the energy behavior of the gasification process with objective to research which feedstock of petroleum coke has a better yield of energy. Effect feed petroleum coke on energy characteristics of the clear synthetic gas (gasl): molar composition of CO and H₂, High Heating Value (HHV_gasl), energy power (Ω_gasl),Cold Gas Efficiency (CGE_gasl) and thermal efficiency of gasification (η_tg) is realized. The parametric study has been realized for 0.64 < oxygen/coke < 1.11 ratio with the flow of oxygen (6036.388 kg/h) and steam/oxygen of 23% both constant. It is observed that in oxygen/coke 0.77 and 0.94 ratio it is present the best energy characteristics of the gasl from CRM and CRC, respectively. The best energy characteristics relationship of the gasl fined are: molar composition CO (65.6, 68.5), H₂ (32.29, 29.13), HHV_gasl (14054.6 kJ/kg_gasl, 13438.76 kJ/kg_gJ, Ω_gasl (204.86 GJ/h, 178.02 GJ/h), CGE_gasl (74.43%, 71.14%), η_tg (86.2%, 83.22%). The gasification of petroleum coke CRM produced energy with 26.20 MJ/kg_coque rates whereas that gasification of the petroleum coke CRC produced 27.74 MJ/kg_coque rates.
