Reformer reaction
Before describing the reaction chemistry of the catalytic reforming process as used in petroleum refineries, the typical naphthas used as catalytic reforming feedstocks will be discussed. A petroleum refinery includes many unit operations and unit processes. The first unit operation in a refinery is the continuous distillation of the petroleum crude oil being …

The initial process, thermal reforming, was developed in the late 1920s. Thermal reforming employed temperatures of 510–565 °C (950–1,050 °F) at moderate pressures—about 40 bars (4 MPa), or 600 psi—to obtain gasolines (petrols) with octane numbers of 70 to 80 …
WebThe Braun Purifier process plants utilized a primary or tubular reformer with a low outlet temperature and high methane leakage to reduce the size and cost of the reformer. Excess air was added to the secondary reformer to reduce the methane content of the primary reformer exit stream to 1–2%. WebApr 13, 2024 · This reaction generates heat for the endothermic steam reforming reactions in the catalytic bed. Thus, autothermal processes self-heat and self-sustain without external heating. The process runs at temperatures and pressures of 900 to 1050°C and 30 to 100 bar, respectively, which are harsher conditions than normal SMR. These conditions ...
WebFeb 19, 2024 · The purpose of this reforming reaction is the production of pure hydrogen gas. Syngas is a mixture of hydrogen gas and carbon dioxide gas. The reaction that is taking place in this reformer is as follows: CH4 + H2O ⇌ CO + 3H2. The above reaction is highly endothermic; it consumes energy from the surrounding. ... WebStep 2) Reforming Reaction Steam from the furnace is mixed with natural gas, which contains methane to start the reaction. The steam-gas mixture enters the reformer from the inlet manifold. The reforming tubes are surrounded by burners, keeping the temperature of the mixture above 1,500 ⁰F. At these temperatures, methane (CH 4) reacts with ...
WebNatural gas reforminginvolves an endothermic reaction of methane and steam at high temperatures according to the following overall process: (19.1)CH4+2H2O→4H2+CO2 The process temperature has to be at least 700°C and up to 1000°C or above to generate a satisfactory yield of hydrogen.
WebEach reactor vessel contains a platinum and alumina catalyst to drive the reaction. Also, for each reactor there is a furnace to inject additional heat as the reaction is endothermic. The product from the reformer (reformate) is a highly aromatic naphtha-range stream, as well as some by-product lighter material and hydrogen.
