Catalyst technologies for improved FCC yields

Article Summary. To improve refinery margins, there is a trend to process heavier, more contaminated crude oil. Consequently, fluid catalytic cracking (FCC) feedstock is getting heavier (see Figure 1). 1 One of these contaminants that can be detrimental is nickel (see Figure 2). 2 Nickel (Ni) deposits on the FCC catalyst particle and catalyses dehydrogenation reactions,

Refining process for removing antimony from lead bullion

Note: Total caustic added was 2.5 lbs. Total refining dross skimmed was 28.3 lbs. From this example, the following observations were made: (a) As seen in Table 2, the first sodium addition results in a low ratio of antimony removal for a pound of sodium added since most of the sodium added in this step goes into solution in the bullion and thus is not available for the antimony removal reaction;
