Abstract
Provided are biogenic porous carbon silicon dioxide compositions, as well as related compositions, and methods of making and using such compositions. Exemplary biogenic porous carbon silicon dioxide compositions include a high-carbon biogenic reagent composition that contains at least about 50 wt % total carbon, at most about 5 wt % hydrogen, at most about 1 wt % nitrogen, at most about 0.5 wt % phosphorus, at most about 0.2 wt % sulfur, at most about 0.02 wt % titanium, at most about 0.5% calcium, at most about 0.1% aluminum, and silicon dioxide. The total carbon can be biogenic carbon, and the silicon dioxide can be contained within river rock or silica fume. Also provided are processes for producing such compositions, where the processes can include: preheating a renewable feedstock, pyrolyzing the renewable feedstock, separating certain pyrolysis products, cooling solid pyrolysis products, and introducing silicon dioxide at a certain point in process.
