Chapter 4 - Methanol reformation-based strategies for using methanol as an internal combustion engine fuel: a brief overview

Abstract

This chapter focuses on using methanol for onboard hydrogen generation in automotive applications. It provides a systematic overview covering the need for hydrogen in internal combustion engines (ICEs), the challenges with its storage, and solving the storage problem through thermochemical recuperation. Thermochemical recuperation, which generates hydrogen from a reforming reaction powered by engine exhaust heat, is discussed in detail. The chapter summarizes various aspects of choosing methanol as a reforming fuel, along with suitable reforming reactions and catalyst selection. Methanol steam reforming and decomposition methods seems efficient for generating onboard hydrogen and furthering its applicability in ICEs. The chapter also sheds light on various ongoing research efforts in methanol-reforming applications in ICEs, aiming to enhance engine efficiency and reduce emissions. Overall, the chapter provides a comprehensive overview of the concept of methanol reforming and its applicability in ICEs by focusing on essential characteristics such as reactor design, engine performance, and emissions control.
