Here, the catalytic effects of sixteen types of solid acid/base additives on the deamination of alanine under hydrothermal conditions at 90–150 °C were examined. As a result, porous sulfonated carbon (FCC-P) showed the highest catalytic activity, which was attributed to the high contents of multiple functional groups like sulfonyl and oxygen functional groups. Using FCC-P as the catalyst, the parameters including the additive amount and alanine solution concentration were optimized to be 0.5 g and ≥ 50 mmol/L, respectively, and the effects of temperature and time were studied detailedly. At 150 °C for 60 min, the deamination yield and alanine conversion achieved to 20.0% and 51.0%, respectively, with the production yield of ammonium at 7.6%. The reusability of two types of sulfonated carbon catalysts was examined. Finally, FCC-P was applied to amino acids including glycine, valine, leucine, and serine, and showed high catalytic activity for each hydrothermal deamination reaction.

在此，研究了在90–150°C的水热条件下，十六种固体酸/碱添加剂对丙氨酸脱氨的催化作用。结果，多孔磺化碳（FCC-P）显示出最高的催化活性，这归因于诸如磺酰基和氧官能团的多个官能团的高含量。以FCC-P为催化剂，将添加量和丙氨酸溶液浓度等参数分别优化为0.5 g和≥50 mmol / L，并详细研究了温度和时间的影响。在150℃下60分钟，脱氨产率和丙氨酸转化率分别达到20.0％和51.0％，铵的产率为7.6％。考察了两种类型的磺化碳催化剂的可重复使用性。最后，
