    摘要: The invention includes a process for reducing the amount of HCN discharged to atmosphere from a FCC unit, having a regenerator and a means for collecting and supporting catalyst particles. The process comprises adding a catalyst to the regenerator flue gas prior to entering the collecting means and precipitating the catalyst in the collecting means to form a catalyst bed. Ammonia or ammonia precursor is optionally added to the flue gas. The flue gas HCN is reacted in the presence of water and oxygen in the flue gas, and optional ammonia or ammonia precursor, at 200° C. to 800° C. in the presence of the catalyst bed to reduce the HCN amount, and the flue gas containing a reduced amount of HCN is discharged to atmosphere. The catalyst is one or more supported transition or lanthanide metal catalysts. The process can also be utilized in any combustion process.

    摘要: Bastnaesite materials and Mg A! (and/or Al B!) materials can be chemically reacted by use of reactions wherein a Al B! ingredient such as alumina is made into a sol by use of a mono-protonic acid before Mg A! (and/or Al B!) materials is (are) reacted with the bastnaesite material. The resulting compounds are then used as SO.sub.x catalyst/absorbent materials in fluid catalytic cracking units and/or in fixed bed units.

    摘要: The present invention is directed to methods for mitigating the deleterious effect of at least one metal on an FCC catalyst. This objective is achieved by using a mixed metal oxide compound comprising magnesium and aluminum, that has not been derived from a hydrotalcite compound, and having an X-ray diffraction pattern displaying at least a reflection at a two theta peak position at about 43 degrees and about 62 degrees, wherein the ratio of magnesium to aluminum in the compound is from about 0.6:1 to about 10:1. In one embodiment, the ratio of magnesium to aluminum in the compound is from about 1:1 to about 6:1. In one embodiment, the ratio of magnesium to aluminum in the compound is from about 1.5:1 to about 10:1. In another embodiment, the invention is directed to methods wherein the ratio of magnesium to aluminum in the compound is from about 1.5:1 to about 6:1.
