Abstract: An improved method for preparing a catalyst which is superior for converting methane to ethane and ethylene is described. The method involves mixing a solution of a magnesium alkoxide in alcohol with a solution of a lithium compound in alcohol. Preferably, chlorine is introduced into the mixture. A solution of an aluminum alkoxide in an alcohol may also be added to the mixture. The magnesium alkoxide is hydrolyzed to produce a gel, and the gel is then calcined to produce the catalyst. Catalysts prepared by this method are superior for converting methane to ethane and ethylene, and have superior selectivities for ethylene and ethane over conventional lithium carbonate/magnesium oxide catalysts.

Abstract: An olefins process is described which combines cracking of a hydrocarbon feedstock with the coupling of methane using an oxygen-affording gas such that the heat evolved in the exothermic methane coupling reaction is effectively transferred to the endothermic cracking process in a manner which does not allow the non-hydrocarbon products in the effluent of the methane coupling reaction to mix with the effluent of the cracking process. By combining the cryogenic requirements of the two processes, the refrigeration used in air liquifaction to separate oxygen for the methane coupling process can provide refrigerant nitrogen to liquify one or more of methane, ethylene and propylene which can be used in the cryogenic separation of the C.sub.2 + hydrocarbon products in the cracking process effluent.

Abstract: A seam cleaning paste, cream or liquid is disclosed, which comprises a hydrocarbon solvent and a finely divided inorganic powder. Treatment of the area near the seams of various types of floor coverings, especially highly stain resistant and soil resistant floor coverings, does not significantly change the appearance of the floor nor its resistance to soiling or staining. Yet it results in much improved adhesion of certain seam coaters subsequently applied to bridge the seam and prevent dirt from lodging therein. These creams do not exaggerate bubble formation in subsequently applied seam coaters and in fact, preferred embodiments help prevent such bubbles from forming.
