His work is crucial in addressing environmental challenges related to carbon emissions.

Latest Patents

One of his latest patents is titled "Method of fabricating medium-high temperature CO2 sorbents made of alkali metal promoted calcium aluminate carbonates." This innovative method synthesizes a dry material using alkali metals such as lithium, sodium, and potassium to create a CO2 sorbent that operates effectively at temperatures exceeding 600 degrees Celsius. The key composition of these sorbents consists of 52% to 69% of CaO, which enhances CO2 capture at temperatures ranging from 400 to 800 degrees Celsius. This breakthrough results in a sintering-resistant sorbent that exhibits an initial carbonation capacity of 50% and maintains a CO2 capturing performance that is 20 times more effective after 40 to 60 hours of operation.

Another significant patent involves a technique for fabricating a medium-high temperature CO2 sorbent of layered nano-carbonate. This sorbent captures CO2 at temperatures above 600 degrees Celsius and incorporates calcium acetate to create a nano-scale layered double hydroxide (LDH). The layered structure facilitates templated synthesis, resulting in a sorbent with an initial conversion rate exceeding 90%, which remains consistent even after 100 carbonation and de-carbonation cycles.
