Extraction of aromatic compounds from catalytic cracking light gas oil with nitromethane

Conclusions It has been shown that nitromethane can be used successfully for separating kerosene-gas oil fractions to obtain raffinates which satisfy the requirements for diesel fuel plus highly aromatized extracts which contain less than 6% of saturated hydrocarbons.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 8, pp. 27–29, August, 1967.     

Mathematical model of the regenerator of a catalytic cracker unit

Conclusions It has been shown that the mathematical model worked out for an industrial regenerator yields satisfactory agreement between the calculated and experimental data on the coke content of the catalyst, the oxygen content in the gas, and the temperatures in the various cross-sections of the regenerator.The best value of the preexponential factor of the regeneration rate constant in an industrial apparatus has been determined.Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 8, pp. 41–43, August, 1967.
