    • The invention proposes a method of oxidative dehydrogenation and cracking of C2-C5 paraffins (homogeneous hydrocarbons or mixtures with liquefied petroleum gas) to form C2-C5 olefins in the presence of an oxygen-containing gas and water vapor using a novel calcined oxidic catalyst that has the following composition: XaYbZcAdOx, wherein X is an element of groups II and/or IVb (Mg, Ca, Ti, Zr...), Y is a lanthanide and/or element of groups IVa or Va (Ce, La, Nd, Dy, Sn, Pr, Sb, Pb...), Z is an element of group I (Li, La, K...), A is an element of group VII (Cl, Br, J), and a is 0.4-0.9, b is 0.005-0.3, c is 0.05-1.5, d is 0.05-0.8 and x is a number determined by the valence requirements of the metals and halogens. The catalyst is used in the form of pressed spherical pellets or extrudates with added binder or deposited on a carrier material that consists of one of the above-mentioned oxidic components or of a separate carrier material. The weight-related space velocity relative to the hydrocarbons used is within the range of 0.1 to 20 h and the temperature is 400 to 700 DEG C.
    • 本发明提出了用于氧化脱氢的方法和在含氧气体和水蒸汽存在的C2-C5链烷烃(artreine烃或诸如液化石油气的混合物),以C2-C5烯烃的裂化,使用一种新型的煅烧氧化催化剂之前,下面 该组合物:XaYbZcAdOx。 其中:X = II族元素和/或IVb族(镁,钙,钛,锆,...),Y =镧系元素和/或组IVA或VA(铈,镧,钕,镝,锡的元素 PR,锑,铅,...)中,Z =基团的元素I(栗,镧,K,...),A = VII族元素(氯,溴,I)和= 0.4至0 9,b = 0.005〜0.3,C = 0.05〜1.5,D = 0.05〜0.8,它是由金属和卤素的化合价要求决定X =号码。 该催化剂在具有球形粘合剂添加或,或从单独的载体材料施加到其由上面提到的氧化组分中的一种的支撑材料压制粒料或挤出物的形式使用。 基于所用的烃的重量时空速为0.1至20小时的范围内<-1>和400至700℃下的温度下
