以联产纳米炭和液体燃料为目的，对载镍木材进行了两步炭化（500° C一步炭化，900° C二步炭化）和常规900 °C一步炭化，比较了两种炭化工艺的可行性。第一次炭化制备的木焦经第二次炭化后，无论是炭的晶体结构还是介孔结构，其二次炭化产物均与一次炭化所得的木焦相当。第二次碳化产生的气体中氢气和二氧化碳的比例分别比一步法大得多和小得多，第一次和第二次碳化产生的气体总量与一步法相当。考虑到二次碳化操作简单，不产生焦油，在实际操作中，二步法工艺上级一步法工艺。此外，通过二次炭化，还获得了木质焦中大孔形成的有用结果。
Carbonization of wood loaded with nickel, which aims at co-production of dual functional nano-carbon and fluid fuels, was conducted by two steps process (500°C-carbonization as the first step followed by 900°C-carbonization as the second one) and usual one step carbonization at 900°C to compare them in terms of practicability. The 2nd carbonization of wood char prepared by the 1st carbonization could produce the 2nd char almost equal to char obtained by one step carbonization of wood in both crystallographic structure of carbon and mesoporous structure. Gases produced by the 2nd carbonization contained hydrogen and carbon dioxide in much larger and smaller proportions, respectively, than those obtained by one step process, and the total amount of gases produced by the 1st and the 2nd carbonizations was equal to that by one step process. When considering easier operation of the 2nd carbonization giving no tar, it is concluded that two steps process is superior to one step process in actual operation. In addition, useful findings of macropore formation in wood char were obtained by the 2nd carbonization.
