▎ 摘　　要

NOVELTY - Vulcanizable rubber composition comprises 100 parts by weight elastomer (phr) of at least one diene-based elastomer, and 1-100 phr of a carbon dioxide-generated carbon reinforcement. The carbon dioxide-generated carbon reinforcement is produced by mixing a first gas stream containing carbon dioxide and a second gas stream containing a gaseous reducing agent to form a reaction gas mixture. The reaction gas mixture is supplied to a reaction zone and the carbon dioxide is reacted with the gaseous reducing agent in the reaction zone in the presence of an iron-containing catalyst to form water and the solid carbon product. The water formed in the reaction zone is separated from the reaction gas mixture during the reaction of the carbon dioxide with the gaseous reducing agent. USE - Vulcanizable rubber composition used in pneumatic tire (claimed) such as race tire, passenger tire, aircraft tire, agricultural, earthmover, off-the-road, truck tire, etc. ADVANTAGE - The vulcanizable rubber composition has improved recycled nature and sustainability.
