  • Process for removing carbonaceous deposits on surfaces of catalysts and plant parts
    Patent number: 8349090
    Abstract: A process for removing carbonaceous deposits on surfaces of catalysts and plant parts by treating the deposits with a superheated stream of steam admixed at least temporarily with an oxygenous gas is provided, which involves, in each case monitoring the offgas CO2 content after condensation of the steam, at a temperature of at least 300° C.: (a) treating the carbonaceous deposits with superheated steam at a temperature of at least 300° C. until the CO2 content of the offgas has exceeded a maximum; (b) then, with further supply of superheated steam, commencing oxygen supply, the amount of oxygen supplied being adjusted such that the CO2 content in the offgas decreases further until it has fallen to a value of <1% by volume; and then (c) ending the supply of superheated steam and passing an oxygenous gas over remaining amounts of carbonaceous deposits until the deposits have been virtually removed.

  • Heat-curable compositions comprising low-temperature impact strength modifiers
    Patent number: 8076424
    Abstract: The present invention relates to compositions which contain at least one epoxide adduct A having on average more than one epoxide group per molecule, at least one polymer B of the formula (I), at least one thixotropic agent C, based on a urea derivative in a nondiffusing carrier material, and at least one curing agent D for epoxy resins, which is activated by elevated temperature. This composition serves in particular as an adhesive and has an extremely high dynamic resistance to cleavage, in particular at low temperatures. The invention furthermore relates to impact strength modifiers terminated with epoxide groups and of the formula (I).
