Abstract Recycling of crosslinked plastics is an intractable challenge due to their very limited amenability mechanical reprocessing. While a variety chemical recycling methods have been recently reported, these systems primarily focus on deconstructing or depolymerizing monomers and liquid fuels, which subsequent use likely involves additional energy consumption greenhouse gas emission. In thi...

Direct sulfonation of methane with SO3 to methanesulfonic acid (MSA) and methylbisulfate was investigated in sulfuric acid using Hg(I), Hg(II), and Rh(III)-salts as catalysts. O2 was found to be an important component for the regeneration of the catalyst. The effects of O2 pressure, temperature, SO3 concentration, methane pressure, and catalyst concentration were examined on the rates of SO3 co...

a type of novel hypercross-linked fiber adsorbent was obtained by sulfonation and cross-linking reaction of polypropylene fiber grafted styrene-divinylbenzene. the aim of the fiber sulfonation and cross-linking method was to prepare rigid three dimensional networks in the entire fiber and change the ion exchange capacity of fiber. the hypercross-linked fiber adsorbent possesses a principally di...

Solid acid catalyst was produced from olive pomace (OP), characterized and used for the esterification of OP oil. pyrolyzed, physical activated by steam sulfonated using sulfuric acid. Commercial, coconut husk-based, carbon (CHAC) also comparison. The activation has shown a significant increase in (OPAC) surface area developing simultaneously its micro meso-porosity. sulfonation further increas...

Production of sodium alpha olefin sulfonates from a variety of normal alpha olefin blends has been studied at the pilot plant scale. Results for the sulfonation, neutralization, and hydrolysis of commercial grade C14, C1416, C1418, and C1224 normal alpha olefins are presented, and the application of a new surfactant drying technology for producing ultra-concentrated AOS is discussed. Physical p...
