Embodiment

[0044] The following examples are provided to better illustrate the embodiments of the present invention, but they should not be construed as limiting the scope of the present invention.

[0045] In the first example, the reaction rates of different variants of the black powder oxygen carrier (as described above) were compared. Specifically, this example compares the reaction rates of activated black powder, non-activated black powder, activated SA7T1100, and non-activated SA7T1100. Black powder (mainly including Fe 3 O 4 ) Collected from a gas pipeline and found in the upstream filter of a natural gas refinery. SA7T1100 as mentioned above is 60.1% black powder and 39.9% Mn 3 O 4 mixture. Reactivity of activated materials treated at 500°C. Use of CH in batch fluidized bed reactors 4 As a fuel, it is studied under the following conditions: a) The particle mass of each group of oxygen carriers is 15g; b) During the oxygen carrier reduction process (CH 4 Combustion) in the flow rat...

Abstract

A process for producing black powder oxygen carriers for use in a chemical looping combustion unit includes the steps of: (a) removing and collecting the black powder waste material that was formed in a gas pipeline; (b) pre-treating the collected black powder to adjust its spherical shape to avoid attrition and fines production; and (c) activating the black powder to increase its reactivity rate and produce the black powder oxygen carrier that is suitable for use in the chemical looping combustion process as an oxygen carrier.

Description

Technical field [0001] The invention relates to a method for generating energy, synthesis gas, hydrogen, heat, etc. by relying on a chemical chain combustion scheme. More particularly, the present invention relates to the use of gas pipeline waste (which was previously discarded) as an oxygen carrier in a chemical chain combustion scheme. Background technique [0002] In recent years, attention to global warming has increased, which has led to an increase in research in the field of power generation. In order to combat the undesirable effects of global warming, different measures have been proposed. One such measure is carbon capture and storage (CCS), which is widely regarded as a countermeasure against CO 2 Medium to long-term mitigation measures for emissions. CCS has the potential to be both valuable and environmentally friendly, and if it is captured after CO 2 Can be used in industrial applications, it can be realized. For example, CO 2 -EOR (by adding CO 2 Enhanced oil ...
