Daim ntawv thov ntawm Lanthhanum Carbonate
Lanthhanum carbonate, yog cov ntaub ntawv raw rau FCC catalyst, iav, dej kho thiab cov tshuaj ntawm fostrol. Lanthhanum-nplua nuj nyob hauv ntiaj teb carbonate tau siv ntau yam rau kev tawm tsam hauv FCC catalalysts, tshwj xeeb tshaj yog tsim cov roj octane los ntawm cov roj nyoos roj. Lanthhanum carbonate tau pom zoo raws li cov tshuaj (fosrenol, shire tshuaj ntsuam xyuas) kom nqus cov neeg mob phosphateStin ntau dua ntawm kev ua tsis tiav.
