Abstract

Methane is converted into other hydrocarbons of low molecular-weight, such as ethylene and ethane by heating at 350-850 DEG C. in contact with catalysts comprising metallic nickel, cobalt, copper, or zinc in the solid or liquid state. Promoters such as aluminium oxide or hydroxide or alkaline earth compounds, and also carriers such as kieselguhr, pumice, silica gel or carborundum may be employed. The formation of ethane is favoured by relatively low temperatures, short time of contact, and unactivated catalysts or catalysts of low activity, whereas the production of ethylene is favoured by more strenuous conditions. Pressures below or above atmospheric may be employed, but preferably not much above atmospheric, such as 1-5 atmospheres. The catalyst may be used in the form of a lining to the reaction tube, especially when narrow tubes are used, which may be lined with nickel; or the catalysts may be used in a liquid bath, for instance, they may be suspended in molten halides of alkali or alkaline earth metals, or molten metals such as lead may be employed in the bath. The methane may be mixed with other hydrocarbons or with different gases or hydrogen. The reaction product may be further treated in any suitable way, except treatment to effect polymerization; for instance the vapours may be recirculated over the catalyst, preferably after first removing the ethylene formed, such removal being effected for instance by absorption in sulphuric, phosphoric, or hypochlorous acid or in active charcoal or silica gel. In an example, a gas containing 60 per cent of methane and 20 per cent of ethane is repeatedly passed through nickel-lined reaction tubes at 600 DEG C. containing a catalyst obtained by depositing nickel oxide and calcium carbonate on pumice and reducing the product in hydrogen; the time of contact is 1 minute at each cycle.ALSO:A catalyst for the conversion of methane into other hydrocarbons of low molecular weight such as ethylene and ethane is made by depositing nickel oxide and calcium carbonate on pumice and reducing in hydrogen.
