A kinetic assessment of the effect of the fractional and chemical composition of the crude on catalytic cracking rate in a fluidized bed

Application of a Kinetic Model for Catalytic Cracking. Effects of Charge Stocks

“…More recently White (1968a,b) correlated catalytic cracking yields with various classes of paraffins, naphthenes, and aromatics based on a mass spectrographie technique of Fitzgerald et al (1970). Shnaider (1969) and Shnaider et al (1969) developed a kinetic scheme for catalytic cracking and studied the effects of chemical compositions of charge stocks on cracking rates in fluidized reactors. Akhmetshina et al (1969) studied the effects of pure hydrocarbons and chemical composition of some petroleum fractions on coke formation on an aluminosilicate catalyst.…”

“…Their analysis included distillation, separations by molecular sieves, mass spectrometry, and ultraviolet spectroscopy. Shnaider et al (1969) recently developed a kinetic model for catalytic cracking and utilized it to analyze the catalytic 538 Ind. Eng.…”

Application of a Kinetic Model for Catalytic Cracking. III. Some Effects of Nitrogen Poisoning and Recycle

“…Reif et al (1961) included basic nitrogen concentration as one of the key parameters in their regression correlations for the prediction of conversion and product yields from the properties of various charge stocks. Schnaider et al (1969) included the effects of basic nitrogen in charge stocks in their kinetic assessment of charge stock properties on the rates of catalytic cracking.…”
