This paper presents techniques and results for simulations of unequal-mass, nonspinning binary black holes with pseudospectral methods. Specifically, we develop an efficient root-finding procedure to ensure the black hole initial data have the desired masses and spins; we extend the dual coordinate frame method and eccentricity removal to asymmetric binaries. Furthermore, we describe techniques to simulate mergers of unequal-mass black holes. The second part of the paper presents numerical simulations of nonspinning binary black holes with mass ratios 2, 3, 4, and 6, covering between 15 and 22 orbits, merger and ringdown. We discuss the accuracy of these simulations, the evolution of the (initially zero) black hole spins, and the remnant black hole properties.
