Reaction Interfacial Study of the Carbonation of San Carlos Olivine
Abstract
The mineral sequestration of CO2 is a candidate technology for reducing the amount of anthropogenic CO2 that is being released into the atmosphere. Olivine (e.g., forsterite, Mg_2SiO_4), a widely available mineral, reacts with CO2 to form magnesite (MgCO_3), which is a mineral capable of immobilizing CO2 over geological time periods. The solid / multiphase interface region can provide key insight to many of the key mechanisms that govern the reactivity of the olivine. Study of this region at the atomic level is necessary to facilitate engineering new materials and processes that will enhance carbonization reactivity and lower process costs. Herein, we will discuss our latest studies of the olivine carbonation reaction interface. We will present data obtained from the reaction interface collected using a variety of analytical techniques, including; HRTEM, EDX, and FESEM.
