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 …

Resilience in the antimony supply chain
The antimony diversity of supply of both mining and refining is low. • Almost 70% of Sb is mined as by- or co-product. • Companion metals can both have higher and lower resilience. • An additional 25% of Sb production comes from post-consumer recycling. • Stockpiling has played a role in dampening and exacerbating supply disruptions.
