Mobile Carbon Capture - Phase 3

ISEF · 2022 Chemistry Fourth Award

Sushkin, Maya · South High Community School

Is this your project?

Overview

A mobile carbon capture device to extract CO2 from car exhaust was designed and built to fit in a normal passenger car, a Toyota Sports Utility Vehicle (SUV). The mobile device was constructed as a fine spray CO2 scrubber using Potassium Hydroxide (KOH) or Sodium Hydroxide (NaOH) solutions as the CO2 absorbents. Measurements were conducted using a commercial CO2 sensor and laptop computer to measure the CO2 content of the car exhaust inflow and outflow of the scrubber over a test period. Results were calculated and presented to determine the mobile scrubber efficiency and comparison of absorbents.
