Abstract

To develop a compact and portable fuel processor, two types of stand-alone methanol fuel processor using a combination of an autothermal methanol reformer, a high-temperature water-gas shift reactor, and an internal burner are presented. On the basis of different waste heat recovery schemes, designs 1 and 2, a flexible waste heat recovery design (design 2) by utilizing the split waste heat flow is verified to reduce the waste heat loss. The specific optimization algorithm for maximizing hydrogen yield is taken into account to determine the optimum operating conditions of designs 1 and 2. Through the feasibility analysis at different operational scenarios, the conflict between the optimum operating conditions and the region of operational feasibility can be found. The simulations show that the flexible waste heat recovery design with additional operating variables can raise 11% hydrogen yield and reduce 3.3% waste heat loss.
