Latest Patents

Lim's latest patents include an "Internally Circulating Fluidized Bed Membrane Reactor System." This invention introduces a novel fluidized bed membrane reactor designed for autothermal operations. It features internal catalyst solids circulation, which facilitates heat transfer between the reforming and oxidation zones. The method involves producing hydrogen gas from hydrocarbon gas and steam by forming a fluidized bed of a suitable particulate catalyst. The catalyst operates in two reaction modes: an endothermic dehydrogenation mode and an exothermic oxidation mode. This innovative approach allows for the effective separation of hydrogen gas from other gases using a perm-selective membrane.

Another significant patent is the "Fluidized Bed Reaction System for Steam/Hydrocarbon Gas Reforming." In this system, hydrogen gas is generated by reacting steam and hydrocarbon gas, such as methane or natural gas, in a fluidized bed of catalytic material. The catalytic material is fluidized by injecting the reacting gases at the bottom of the bed. The generated hydrogen is removed through a selectively permeable membrane, ensuring efficient hydrogen production.
