Abstract: The invention relates to a free-radical initiator composition for polyolefin modification comprising a peroxide-modified inorganic solid particle prepared from: i) a liquid or solution of hydrogen peroxide, and ii) one or more inorganic solid particles, wherein the inorganic solid particles have affinity to the hydrogen peroxide through hydrogen bonding. The invention also relates to a method for preparing a peroxide-modified inorganic composition, comprising mixing a liquid or solution of hydrogen peroxide and one or more inorganic solid particles to form a suspension or gel, and optionally, filtering the suspension or gel and drying the filtered materials to form a solid, peroxide-modified inorganic composition.

Abstract: A catalyst composition includes a metal catalyst dispersed in a molten eutectic mixture of alkali metal or alkaline earth metal carbonates or hydroxides. A process for the catalytic cracking of hydrocarbons includes contacting in a reactor system a carbon-containing feedstock with at least one catalyst in the presence of oxygen to generate olefinic and/or aromatic compounds; and collecting the olefinic and/or aromatic compounds; wherein: the at least one catalyst includes a metal catalyst dispersed in a molten eutectic mixture of alkali metal or alkaline earth metal carbonates or hydroxides. A process for preparing the catalyst includes mixing metal catalyst precursors selected from transition metal compounds and rare-earth metal compounds and a eutectic mixture of alkali metal or alkaline earth metal carbonates or hydroxides and heating it. A use of the catalyst in the catalytic cracking process of hydrocarbons.
