In this study, carbon foams prepared from the by-products of the Finnish forest industry, such as tannic acid and pine bark extracts, were examined as supports for 5/5% Cu/Ni catalysts in the hydrotreatment of furfural to 2-methylfuran (MF). Experiments were conducted in a batch reactor at 503 K and 40 bar H2. Prior to metal impregnation, the carbon foam from tannic acid was activated with steam (S1), and the carbon foam from pine bark extracts was activated with ZnCl2 (S2) and washed with acids (HNO3 or H2SO4). For comparison, a spruce-based activated carbon (AC) catalyst and two commercial AC catalysts as references were investigated. Compressive strength of the foam S2 was 30 times greater than that of S1. The highest MF selectivity of the foam-supported catalysts was 48 % (S2, washed with HNO3) at a conversion of 91 %. According to the results, carbon foams prepared from pine bark extracts can be applied as catalyst supports.

在生物基碳泡沫上负载的CuNi催化剂将糠醛转化为2-甲基呋喃

在这项研究中,研究人员考察了由芬兰森林工业的副产品(如单宁酸和松树皮提取物)制得的碳泡沫,作为糠醛加氢处理成2-甲基呋喃的5/5%Cu / Ni催化剂的载体( MF)。在间歇反应器中于503 K和40 bar H 2进行实验。在金属浸渍之前,单宁酸的碳泡沫用蒸汽(S1)活化,松树皮提取物的碳泡沫用ZnCl 2(S2)活化并用酸(HNO 3或H 2 SO 4)洗涤)。为了进行比较,研究了一种基于云杉的活性炭(AC)催化剂和两种商用AC催化剂。泡沫S2的抗压强度比S1大30倍。泡沫负载的催化剂的最高MF选择性为48%(S 2,用HNO 3洗涤),转化率为91%。根据结果​​,由松树皮提取物制备的碳泡沫可用作催化剂载体。
