  • Patent number: 4132065
    Abstract: A free-oxygen containing gas is heated while under pressure in a gas fired pressurized heater and then reacted with a hydrocarbonaceous fuel optionally in the presence of a temperature moderator in the reaction zone of a free-flow partial oxidation gas generator. The effluent gas stream from the gas generator is cooled, cleaned and optionally purified to produce a H.sub.2 +CO-containing product gas. One portion of said product gas is reacted in said pressurized heater with air in order to heat the free-oxygen containing gas going into the gas generator. Another portion of said product gas is burned with air in the combustor of a gas turbine. The exhaust gas from the combustor is passed through an expansion turbine to produce mechanical power for compressing the free-oxygen containing gas and air used in the system. The turbine may also drive a turboelectric generator. At least a portion of the flue gas from the fired pressurized heater may be introduced into the combustor or into the expansion turbine.

  • Patent number: 4132744
    Abstract: This invention relates to a process for selectively separating olefins from liquid, aliphatic olefin-paraffin mixtures, said olefins and paraffins each containing from 6 to 20 carbon atoms. Separation is effected by a liquid-liquid extraction technique, using solutions of silver or copper salts in alkanols, or mixed alkanol-aliphatic polyethers solvents, as the extracting media.

  • Patent number: 4125475
    Abstract: This invention concerns the use of certain biogradable detergents containing as their sole active surfactant component linear, paraffinic alcohols containing 6 to 18 carbon atoms. These fatty alcohols have good laundering activity particularly to launder soiled cotton. These alcohols can be formulated in an aqueous solution containing only builders or optionally they can be formulated as multicomponent solid detergents in the form of a homogeneous, free-flowing powder. Using standard laundering tests these materials function well as detergents at low concentration levels, exhibit comparable or superior surfactant activity to sulfonated alkylated benzenes in the removal of soil from cotton or other cellulosics.

  • Patent number: 4076683
    Abstract: Molding compositions or masses comprising sand and a two-component binder system are prepared. These two-component binders consist essentially of 1) polyisocyanate and 2) a low molecular weight polymethylol produced by the controlled condensation of narrow mole ratios of acetone and formaldehyde under alkaline reaction conditions followed by acidification and removal of sufficient water to produce a minimum solid content of at least 95%. These molding compositions cure so fast that they may be taken off the mold five minutes after having been cured with an amine curing agent, and reach a substantial bending strength within minutes of curing compared to prior art compositions which achieve comparable bending strength only after a period of as long as one hour.
