摘要： A method includes producing an unsaturated organic compound from an organic component of an organic-containing feed. A reactor is provided which contains a molten metal bath. The molten metal bath includes a metal, such as a suitable transition metal, which can interact with an organic component of the feed. The feed is directed into the molten metal bath at a rate which causes the metal to interact with the organic component. Operating conditions are established and maintained in the reactor to cause the metal to interact with the organic component. At least one carbon-carbon double bond is formed in the organic component to produce an unsaturated organic compound that is discharged from the molten metal bath.

摘要： There is provided a process for converting propane to ethylene over a zeolite catalyst comprising ZSM-23. This zeolite may be contacted with an anhydrous acidic oxide gas capable of accepting hydrogen by reacting therewith, such as sulfur dioxide (SO.sub.2), in order to enhance the ethylene selectivity of the conversion. The zeolite may either be pretreated with this acidic oxide gas or contacted in situ by cofeeding the acidic oxide gas along with the propane reactant. Particularly in view of the tendency of zeolites such as ZSM-5 to further convert olefins produced into aromatics and other hydrocarbons, the large degree of ethylene selectivity achieved by the process of the present invention is surprising.
摘要翻译：提供了一种在包含ZSM-23的沸石催化剂上将丙烷转化为乙烯的方法。该沸石可以与能够通过与二氧化硫（SO 2）反应而与氢反应而接受氢的无水酸性氧化物气体接触，以提高转化率的乙烯选择性。沸石可以用这种酸性氧化物气体进行预处理，或者通过与酸性氧化物气体一起与丙烷反应物一起进料而原位接触。特别是考虑到诸如ZSM-5的沸石进一步将生产的烯烃转化为芳族化合物和其它烃的倾向，本发明方法获得的大量乙烯选择性是惊人的。

摘要： Compositions of matter comprise oxides of silicon, aluminum and/or titanium mixed with combinations of manganese oxide and magnesium oxide; iron oxide and magnesium oxide; calcium, strontium, barium, tin and/or antimony oxides, manganese oxide and magnesium oxide; and iron oxide, manganese oxide and magnesium oxide. These compositions are particularly useful as catalysts for selectively converting propane and butanes to ethylene and ethane and particularly to ethylene. A method for converting propane and butanes to less saturated hydrocarbons is also disclosed in which the catalyst life is extended and the selectivity to ethylene and ethane, particularly ethylene, is improved by carrying out the contacting with the catalyst in the presence of steam, when the catalyst contains an oxide of iron and, optionally, when the catalyst does not contain an oxide of iron.

摘要： Novel compositions of matter include: mixed oxides of (a) at least one oxide of chromium, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals, preferably lanthanum and cerium, and/or niobium; (b) at least one oxide of chromium, at least one oxide of calcium, strontium, tin and/or antimony, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals and/or niobium; (c) at least one oxide of chromium, at least one oxide of iron and at least one oxide of magnesium, Lanthanum Series metals and/or niobium; and (d) at least one oxide of chromium, at least one oxide of iron, at least one oxide of manganese and at least one oxide of magnesium, Lanthanum Series metals and/or niobium. These compositions are particularly effective as catalyst compositions for the conversion of C.sub.3 and C.sub.4 hydrocarbons to less saturated hydrocarbons, with high selectivities to ethylene and ethane and particularly ethylene, and the addition of the chromium significantly extends the activity of the catalyst for such selective conversion before regeneration is necessary. A method of converting C.sub.3 and C.sub.4 hydrocarbons to less saturated hydrocarbons, and selectively to ethylene and ethane and particularly ethylene, is also disclosed. Carrying out the process in the presence of steam is essential to the process when the catalyst contains iron and is optional when the catalyst does not contain iron. Limiting the amount of bound or fixed sulfur in the catalyst also improves the catalyst.
