The present disclosure broadly relates to processes for preparing iron and ferro-alloys using coffee as a source of carbon.
Claims44
A process for preparing iron comprising:
- (a) forming a mixture comprising iron oxide and a carbon source which is, or is obtained from, coffee;
- and
- (b) heating the mixture for a period of time sufficient to convert the iron oxide to iron.
Use of a carbon source which is, or is obtained from, coffee for preparing iron from iron oxide.
A process for preparing a ferro-alloy, wherein the process comprises the step of addition of a carbon source which is, or is obtained from, coffee.
Use of a carbon source which is, or is obtained from, coffee, in the preparation of a ferro-alloy.
A carbon-containing material obtained by heating coffee, the carbon-containing material having an enriched fixed carbon content as compared to the coffee before heating.
A process for generating hydrogen in situ, the process comprising heating coffee under conditions suitable to liberate hydrogen.
