Abstract
A system to convert a renewable lower energy material to a higher energy material using residual heat from a steel processing unit is provided. A system comprising a flow through catalytic reactor that selectively catalytically converts methanol into a hydrogen and carbon monoxide stream utilizing a steel processing unit's residual heat, and the subsequent separation and collection and storage of hydrogen with the introduction of the separated carbon monoxide stream into the steel processing unit so as to replace or reduce carbon sources, is also disclosed.
Claims26
A system comprising:
- a steel processing unit having a residual heat source;
- at least one conversion reactor configured to receive a first material having a first heating value, the at least one conversion reactor being coupled to the residual heat source, the at least one conversion reactor configured to catalytically convert the first material to a second material having a second heating value greater than the first heating value.
A method comprising:
- providing at least one conversion reactor thermally coupled to a residual heat source of a steel processing unit;
- receiving a first material having a first heating value, wherein the first material is methanol;
- catalytically converting the first material to a second material having a second heating value greater than the first heating value, wherein the second material is hydrogen.
A method of reducing or eliminating solid carbon introduction into a steel process, the method comprising:
- providing at least one conversion reactor thermally coupled to a residual heat source of a steel processing unit;
- receiving methanol in the at least one conversion reactor;
- catalytically converting the methanol to a carbon monoxide stream and a hydrogen stream;
- separating the carbon monoxide stream from the hydrogen stream;
- and
- introducing the carbon monoxide stream into the steel processing unit so as to reduce or eliminate solid carbon introduction.
