Subnano-ceramic membranesA revolutionary separation process
Subnano-ceramic membranesA revolutionary separation process
Gas separation by molecular sieve technique
Subnano-ceramic membranes* are ceramic filters with micropores smaller than one nanometer.
Molecules in gases can be separated by passing through the micropores in the membrane. This technology is currently drawing attention for its role in a revolutionary separation process based on the molecular sieve technique.
*The term subnano refers to dimensions smaller than one nanometer (one billionth of a meter).
Can we apply the strengths of molecular sieve technique to address energy issues?
Subnano-ceramic membranes
Separation equipment based on the subnano-ceramic membranes is capable of dramatically reducing CO2 emissions at lower cost compared to previous methods. The equipment also has small-footprint and requires less energy. Even under conditions of high pressure and high CO2 concentrations, it also delivers outstanding performance and service life superior to traditional equipment based on polymer membranes.
In natural gas refining, this technology reduces loss in separation to one-tenth achieved with polymer membranes, even in gas fields with high impurity concentration—it is often avoided in the past due to high refining costs. The technology promises to expand energy supply and advance environmental protection.

Affordable and Clean Energy
Ensure access to affordable, reliable, sustainable and modern energy
target 7.A
By 2030, enhance international cooperation to facilitate access to clean energy research and technology, including renewable energy, energy efficiency and advanced and cleaner fossil-fuel technology, and promote investment in energy infrastructure and clean energy technology
Climate Action
Take urgent action to combat climate change and its impacts
target 13.1
Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries
Reducing CO2 emissions by separating, capturing, and reusing CO2 in crude oil production
Subnano-ceramic membranes are also expected to find applications in crude oil production.
The crude oil in oil fields accumulates inside tiny openings in rock formations. Primary oil recovery, in which natural energy is used to recover crude oil, typically recovers just 5-25% of it. Even secondary oil recovery, in which water is injected into underground oil strata, recovers only about 30-40% of it.
Carbon dioxide enhanced oil recovery (CO2 EOR), a tertiary oil recovery method, further increases oil recovery rates by injecting CO2 into the underground oil strata to reduce the viscosity of the oil.
Subnano-ceramic membranes could be used to separate CO2 in associated gases from oil fields implementing CO2 EOR.
Reports indicate about one-half of the CO2 injected remains sequestered underground. This method is increasingly introduced as a carbon capture and storage (CCS) solution that is a technology to capture CO2 and store it underground.

PM removal filtersEliminating harmful particulate matter (PM)
PM removal filtersEliminating harmful particulate matter (PM)
PM removal filters that clean automotive exhaust
PM removal filters are made of porous ceramics.
Examples of porous materials include sponges or pumices, which contain numerous fine openings. When exhaust gases are passed through a porous ceramic barrier, the fine openings trap harmful particulate matter (PM), allowing only clean gas to pass.
NGK's products help build a brighter future.
Incorporated into highly permeable masks, ceramics can help protect the air we breathe.
In general, smaller pores means filters are less permeable and more resistant to the passage of exhaust, reducing vehicle fuel efficiency. NGK's PM removal filters offer both effective PM capture and outstanding permeability and heat resistance. By achieving both improved fuel efficiency and cleaner exhaust, they help protect air quality.

Good Health and Well-Being
Ensure healthy lives and promote well-being for all at all ages
target 3.9
By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination.
