  • Process for enhancing the sulfur capture capability of an alkaline earth material
    Patent number: 6594553
    Abstract: The present invention provides, according to one aspect thereof, a computer controlled process for reducing SO2 from a flue gas. The process includes the basic steps of providing an aqueous treatment solution containing an inorganic salt and a control unit for controlling the introduction of the aqueous treatment solution containing an inorganic salt and controlling the control unit in response to a computer program to effect introduction of the aqueous treatment solution into contact with alkaline earth material. Thereafter, the process includes heating the alkaline earth material in the presence of the flue gas containing SO2 to remove the SO2. The alkaline earth material may be limestone or dolomite. The inorganic salt is selected from the group consisting of thermally decomposable sodium compounds including sodium carbonate, sodium bicarbonate, sodium hydroxide, sodium nitrate, and sodium acetate.

  • Oxydehydrogenation of isobutyric acid and its lower alkyl esters
    Patent number: 4434298
    Abstract: Isobutyric acid or a lower alkyl ester thereof is oxidatively dehydrogenated in the vapor phase producing the corresponding .alpha.,.beta.-olefinically unsaturated derivative by contact with a heterogeneous catalyst in the presence of molecular oxygen. The catalyst is composed of the calcined mixture of salts of titanium and iron.
