低含水率脱水污泥超临界水气化制氢用复合催化剂及其应用
摘要：
本发明涉及一种低含水率脱水污泥超临界水气化制氢用复合催化剂及其应用，属于脱水污泥超临界水气化制氢用复合催化剂领域。该低含水率脱水污泥超临界水气化制氢用复合催化剂，包括按照质量份数计的如下原料：活性镍50~75份、固碳剂25~50份，其中所述固碳剂为NaOH、KOH、Ca(OH)2、CaO、CaSiO3或Na2SiO3中的一种。本发明复合催化剂可在较低反应温度下(400℃)催化低含水率脱水污泥产氢，催化效率高，大大节省成本，通过该复合催化剂的使用，在5%添加量条件下，可生成氢气含量高达88%的富氢气体，有效提高了氢气化效率，催化效果显著。
摘要（英）：

The invention relates to a composite catalyst for preparing hydrogen through supercritical water gasification of low-moisture-content dehydrated sludge and an application of the composite catalyst, and belongs to the field of composite catalysts for preparing hydrogen through supercritical water gasification of dehydrated sludge. The composite catalyst for preparing hydrogen through supercritical water gasification of the low-moisture-content dehydrated sludge comprises the following raw materials in parts by mass: 50-75 parts of active nickel and 25-50 parts of a carbon fixation agent, wherein the carbon fixation agent is one of NaOH, KOH, Ca(OH)2, CaO, CaSiO3 or Na2SiO3. The composite catalyst provided by the invention can be used for catalyzing the low-moisture-content dehydrated sludge at a relatively low reaction temperature (400 DEG C) to generate hydrogen, the catalytic efficiency is high, the cost is greatly saved, and by using the composite catalyst and under the condition with 5% of add amount, a hydrogen-rich gas of which the hydrogen content reaches 88% can be generated, the hydrogenation efficiency is improved and the catalytic effect is significant.
