Monte Carlo simulations and finite-size scaling analysis have been carried out to study the critical behavior in a submonolayer lattice-gas which mimics a nanoporous environment. In this model, the adsorbent is modeled as one-dimensional channels of equivalent adsorption sites arranged in a triangular cross-sectional structure. Two kinds of lateral interaction energies have been considered: (1) wL interaction energy between nearest-neighbor particles adsorbed along a single channel and (2) wT interaction energy between particles adsorbed across nearest-neighbor channels. We focus on the case of repulsive transverse (wT >0) and attractive longitudinal (wL
