11638909 · 2023-05-02 · ·

The present disclosure is directed to processes for the selective separation of carbon dioxide (CO.sub.2) from multi-component feedstreams containing CO.sub.2. The processes use a potassium-form MER framework type zeolite having a stick-like morphology. The potassium is present in the zeolite as K.sup.+ in extra-framework locations, and the zeolite is essentially free of an extra-framework cation other than potassium.

INTEGRATED GREEN ENERGY AND SELECTIVE MOLECULAR SEPARATION SYSTEM, AND PROCESS OF GENERATING ELECTRICITY AND SELECTIVELY SEPARATING AND CAPTURING PREDETERMINED MOLECULES PRESENT IN SURROUNDING ENVIRONMENT (GREEN ENERGY BLUE)
20230147875 · 2023-05-11 ·

A green energy generating system (e.g., thermal, solar, wind, kinetic) is integrated with a selective molecular separation (i.e., greenhouse gas capturing) system. The output of each system is utilized by the other to form a unitary system that produces green energy (i.e., electricity) while separating/capturing predetermined molecules (e.g., greenhouse gases) from the environment. The process includes providing kinetic energy fluid from an energy source; driving a turbine via the kinetic energy fluid; driving a generator via the turbine to generate electricity; supplying (i) the kinetic energy fluid exiting the turbine and/or (ii) electricity generated by the generator to a molecular separation unit; intaking the predetermined molecules into the separation unit and selectively separating at least one predetermined molecule from other molecules; and capturing the predetermined molecule via a desorption process using heat from thermal energy of (i) the kinetic energy fluid and/or (ii) an electrical heater powered by the electricity.
