“…The selectivity of Ru/HPS could reach 97% in the hydrogenation of lactose to lactitol with catalyst loading ratio of only 4.9% . Similarly, the Ru/HPS catalyst reached the 98% selectivity toward maltitol in the hydrogenation of maltose . The Ru/C catalyst was also effective for the hydrogenation of sugar mixtures.…”

Because of its chemical structure, low‐cost production, and large‐scale production, lactose is a promising source for the production of sugar alcohols. Lactitol is the primary sugar alcohol derived from lactose through a set of chemical reactions known as catalytic hydrogenation. Reaction products are strongly dependent on the reaction conditions and catalyst type. The purpose of this review is to examine the production of lactitol through hydrogenation of lactose. Technological aspects of hydrogenation of lactose are examined, including primary and secondary reaction products, type of catalyst used, catalyst deactivation and regeneration, kinetic models, selectivity, and reaction mechanisms. Research in this area is not as advanced as enzymatic catalysis, and there are opportunities for further studies in the fields of reaction optimization and detailed characterization of products.

“…В данной работе мы использовали полимерные Ru-содержащие катализаторы, нанесенные на различные типы сверхсшитого полистирола. Эти катализаторы показали высокую активность и селективность при гидрировании моно-и дисахаридов, а также левулиновой кислоты [13][14][15]. Таким образом, было исследовано влияние типа носителя и нагрузки Ru на гидрирование стеариновой кислоты.…”

Данная работа посвящена изучению гидрирования жирных кислот с целью получения жирных спиртов, которые являются ценными продуктами химической промышленности. В процессе гидрирования использовались катализаторы на основе рутения импрегнированного в сверхсшитый полистирол (СПС). Оценивалось влияние типа носителя и содержания металла на выход продуктов гидрирования. Использовались три разных типа СПС: нефункционализированный, с функциональными амино- и сульфогруппами. Анализ результатов показал, что Ru-содержащие катализаторы являются перспективными в гидрировании карбоксильной группы жирных кислот. Ru, стабилизированный СПС с аминогруппами, показал высокий выход стеарилового спирта (86,5%) при высокой конверсии субстрата (90%). Показано, что 1% Ru/MN100 является наиболее эффективным катализатором, который сохраняет свою активность как минимум в 5 последовательных циклах. The current work is devoted to the study of fatty acid carboxylic group hydrogenation in order to obtain fatty alcohols which are the valuable products for fine chemistry. The catalysts based on the ruthenium impregnated into hypercrosslinked polystyrene (HPS) were used in the process. The influence of the type of the support and metal loading on the yield of hydrogenation products was evaluated. Three different types of HPS were used as the catalyst supports non-functionalized, modified with amino- and sulfonic groups. The catalyst based on HPS modified with sulfonic groups showed good selectivity towards the formation of stearic aldehyde, however, was found to be unstable under the reaction conditions. Ru embedded on the HPS modified with amino groups showed a high yield of stearyl alcohol (86.5%) at high substrate conversion (90%). The analysis of the results showed that Ru-containing catalysts can be concerned the permissive in the carboxylic group reduction of fatty acids. 1% Ru/MN100 showed was found to be the most effective catalyst remaining its activity at minimum 5 multiple reuses.

“…Generally, maltose hydrogenation is carried out in a batch slurry reactor. Studies on hydrogenation reactions of maltose in conventional batch slurry reactors can be found in literature [1][2][3][4][5][6][7][8]. The drawback of this conventional reactor is a poor contact between reactant and catalyst.…”

Hydrogenation of Maltose in Catalytic Membrane Reactor for Maltitol Production

et al. 2018

Maltitol is one of the low-calorie sweeteners which has a major role in food industries. Due to its characteristics of comparable sweetness level to sucrose, maltitol can be a suitable sugar replacement. In this work, catalytic membrane reactor (CMR) was examined in maltitol production through hydrogenation of maltose. Commercial ceramic membrane impregnated with Kalcat 8030 Nickel was used as the CMR. The reaction was conducted at a batch mode operation, 95 to 110°C of temperature, and 5 to 8 bar of pressure. In the range of working conditions used in this study, up to 47% conversion was achieved. The reaction conversion was significantly affected by temperature and pressure. Results of this preliminary study indicated that CMR can be used for hydrogenation of maltose with good performance under a relatively low operating pressure.
