The present invention discloses a method, apparatus and method of manufacturing an apparatus; all to produce hydrogen gas, particularly synthesis gas. Preferred embodiments of the invention include an alpha alumina membrane which has been treated with a TiOwash coat on one side and has an active gamma alumina layer on an opposite side. A metal catalyst, preferably rhodium, is deposited within the pores of the alumina. Oxygen travels through the membrane and is activated before contacting methane on the other side of the membrane and forming synthesis gas through partial oxidation of the methane. Embodiments of the invention have a number of benefits including the high conversion rate of oxygen (100%), the separate feed streams of methane and oxygen which allow for optimal ratios to be used without danger of explosion, and the opportunity to vary the feed rates without changing the products formed.

Membrane apparatus and method of preparing a membrane and a method of producing hydrogen

A process utilising the gases carbon monoxide, carbon dioxide and hydrogen to produce alcohols directly, comprises the steps of bringing a fluid mixture comprising carbon monoxide, carbon dioxide and hydrogen into contact with the surfaces of a supported tubular porous catalyst membrane having a range of pore sizes including micropores, mesopores and macropores, controlling the temperature of the said catalyst membrane, maintaining a pressure over said catalyst membrane of from 88 to 600 kPa, and recovering alcohol containing product formed by contact of the fluid mixture with said catalyst membrane.

Embodiments of the invention have a number of benefits including the high conversion rate of oxygen (100%), the separate feed streams of methane and oxygen which allow for optimal ratios to be used without danger of explosion, and the opportunity to vary the feed rates without changing the products formed. Normally gaseous hydrocarbons recovered from remote oil wells (e.g. offshore oil wells) can thus be converted to synthesis gas and then to normally liquid hydrocarbons via a Fischer-Tropsch type reaction. The normally liquid hydrocarbons are easier to transport away from the remote oil well than normally gaseous hydrocarbons.

An apparatus and method to separate a mixture of gases&#x2014;such as carbon dioxide and methane&#x2014;by an inorganic membrane comprising a ceramic support and a silica layer made from a silicon elastomer sol. The apparatus and method can efficiently separate the gaseous mixture and can also cope with the extreme conditions found in e.g. hydrocarbon producing wells. A method of manufacturing the apparatus is also disclosed.
