In this article, a steady-state fractional order boundary-value problem is considered with a fractional convection term. The highest-order derivative term involves a mixed-fractional derivative which appears as a combination of a first-order classical derivative and Caputo fractional derivative. We propose an $L1-$scheme over a uniform mesh for the numerical solution of the fractional differential equation. With the help of a properly chosen barrier function, we discuss error analysis and prove that the proposed method converges with almost first-order. The proposed scheme is also applied on a semilinear fractional differential equation. Numerical experiments are presented to validate the proposed method.
