This work reresents our first ste toward fulfilling active utilization of inherent nonlinearity in ractical chemical reaction systems to increase their efficiency and/or to imrove their controllability. The reaction system investigated numerically was methanol conversion to light olefms such as ethylene and roylene in a tubular fixed-bed reactor. To make use of nonlinearity in the system, the reactor wall temerature was set to vary sinusoidally along its axis instead of a constant wall tem erature. As a result, we found that significant imrovement in selectivities of the desired roducts can be obtained by adequately setting the wall temerature.
