认识到对水蒸汽转化制氢过程有若干设计上的重要考虑,需要对构成该工艺的多单元给予详尽的注意。设计方向首先集中于改进H_2/CO 合成气的发生这个首要单元。1 合成气的发生天然气、液化气、煤及焦炭均为生产氢气的潜在原料。作为生产合成气工艺过程的第一步,可采用的工艺有:(1)水蒸汽转化法;(2)氧气和水蒸汽的自热式转化法;(3)氧气的部分氧化法(POX)。目前大多数的合成气是由天然气、轻烃直至石脑油的水蒸汽转化法制得的。虽然重油及
It is recognized that there are several design considerations that are important to the steam reforming process for hydrogen production and that detailed attention needs to be paid to the multiple units that make up the process. The design direction first focused on improving the H 2 / CO syngas generation as the primary unit. 1 Syngas Generation Natural gas, liquefied gas, coal and coke are potential raw materials for the production of hydrogen. As the first step in the process of producing syngas, the following processes are available: (1) steam reforming; (2) autothermal conversion of oxygen and steam; (3) partial oxidation of oxygen (POX) . At present, most of the syngas is produced by the steam reforming of natural gas, light hydrocarbon and naphtha. Although heavy oil and
