    Abstract: For the oxidative dehydrogenation of saturated carboxylic acids to form .alpha.,.beta.-unsaturated carboxylic acids, saturated acids are contacted with a gas containing molecular oxygen and, where appropriate, an inert diluent gas, in the vapor phase, at a reaction temperature of 250.degree. to 600.degree. C., in the presence of a catalyst system comprising a non-supported catalyst of the formula FeP.sub.x Me.sub.y O.sub.z, wherein: Me is at least one of the following elements: Li, Na, K,, Rb, Cs, Mg, Ca, Sr and Ba; x has a value from 0.2 to 3.0; y has a value from 0.01 to 0.2; and z is the quantity of oxygen bonded to the other elements and corresponding to their oxidation state, in an entrained-bed reactor and, where appropriate, in the presence of steam in a molar ratio to the saturated acid not exceeding 0.5. The catalyst is beneficially associated with at least one zeolite, preferably in a concentration sufficient to improve the attrition resistance of the catalyst, e.g., in an amount by weight of about 1-10% of the catalyst.

    Abstract: A ferritic, heat-resistant steel whose behavior at high application temperatures is improved by the combined addition of oxygen affinitive elements. Apart from stabilizing the electric resistance of heating elements by addition of zirconium, titanium and rare earth metal, also the creep elongation of the steel is considerably reduced under load at temperatures above 900.degree. C., the thermal stress capacity thus being increased. The resulting complex oxide coating increases the protective function with regard to preserving the metallic cross-section in continuous and/or cyclic heat treatments.The steel is composed of:up to 0.10 % Cup to 0.80 % Si0.10 to 0.50 % Mnup to 0.035 % Pup to 0.020 % S12 to 30 % Cr0.10 to 1.0 % Moup to 1 % Ni3.5 to 8 % Al0.01 to 1 % Zr0.003 to 0.8 % rare earth metals0.003 to 0.30 % Ti0.003 to 0.050 % Nremainder Fe and incidental impurities.
