METHANE TO METHANOL CONVERSION
Single iron atoms embedded in graphene can catalyse the conversion of methane into methanol at room temperature. Dependent upon the flow of gas from the well, a reactor vessel will be built and housed in a building heated by the raw gas to a temperature of seventy degrees Fahrenheit. This catalyst is carried on a bed of zeolite which will remove nitrogen and nitrogen compounds in adsorption process, as well as some sulphur and a good percentage of carbon dioxide. Iron—nitrogen—carbon (Fe—N—C) acts as the most satisfactory alternatives to platinum for the oxygen reduction reaction (ORR).

Fiber reinforced zeolite extrudates with enhanced physical properties
The invention relates to a method of making a reinforced catalytic microporous and/or mesoporous bound composition comprising the steps of: providing a pre-formed catalytic crystalline material; mixing the catalytic crystalline material with water, a metal oxide binder, and a reinforcing glass fiber to form an extrudable composition; extruding the extrudable slurry under conditions sufficient to form the reinforced catalytic bound extrudate; and calcining the reinforced catalytic bound extrudate at a temperature and for a time sufficient to form a calcined reinforced catalytic bound catalyst. Advantageously, the reinforcing glass fiber can have a diameter from 5-100 microns and a length-to-diameter ratio from 300:1-3000:1 and can be present in an amount from about 1-50 parts, based on about 1000 parts combined of catalytic crystalline material and metal oxide binder.
