“…Although the earlier studies led to the development of a highly active and selective catalyst for hydrogenation of carboxylic acid derivatives, they did not reveal the precise nature of the catalytically active Re species. Moreover, little is known about the nature of the active species in a number of valuable Re promoted transformation [32][33][34][35][36][37][38][39][40][41][42] despite having been the subject of scientific investigations for years. [43][44][45][46][47][48][49][50][51][52][53][54][55] The main reasons for this are that Re often is highly dispersed on supports and is difficult to be reduced, and it can exist in a variety of oxidation states.…”

“…Breit and co‐workers also reported a similar catalyst system of Pd/Re/C (Re 10 wt%, Pd 2 wt%) (Table , entry 13) to the ReO x ‐Pd/SiO 2 catalyst as described above, although the molecular sieve seems to be necessary for the reaction system. High yield (87%) of the target alcohol was obtained by hydrogenation of stearic acid at 403 K and 2 MPa H 2 , and the catalyst was applicable to the reactions of various carboxylic acids including adipic acid and aromatic carboxylic acids.…”

Hydrogenation of carboxylic acids is an important organic reaction for the synthesis of alcohols, aldehydes, alkanes, and so on. Selective hydrogenation of carboxylic acids to alcohols is particularly important because alcohols are useful and valuable chemicals. However, the hydrogenation of carboxylic acids is difficult due to the low reactivity of the carboxy group and the acidic property, which require rational design of catalysts. Up to now, various effective homogeneous and heterogeneous catalysts have been intensively developed, and remarkable advances have been made in heterogeneous catalysts. In this minireview, recent progress (2010 and after) on the development of heterogeneous catalysts for hydrogenation of carboxylic acids to alcohols, particularly for monocarboxylic acids to mono primary alcohols, is reviewed. The reported literatures were categorized in terms of catalyst systems, such as monometallic catalysts and bimetallic catalysts. The characteristics, particularly the structure of active sites, reaction mechanism and stability, were introduced.

“…In addition, noble metal catalysts such as Pt, Pd and Ru, which have high activity in hydrodeoxygenation, are also suitable for conversion of algal oil into high-grade hydrocarbons [130,131]. Xu et al explored a technology for selective extraction of neutral lipid from algae Scendesmus dimorphus and subsequently conversion into jet fuel [132].…”

The depletion of fossil fuel has drawn growing attention towards the utilization of renewable biomass for sustainable energy production. Technologies for the production of algae derived biofuel has attracted wide attention in recent years. Direct thermochemical conversion of algae obtained biocrude oil with poor fuel quality due to the complex composition of algae. Thus, catalysts are required in such process to remove the heteroatoms such as oxygen, nitrogen, and sulfur. This article reviews the recent advances in catalytic systems for the direct catalytic conversion of algae, as well as catalytic upgrading of algae-derived oil or biocrude into liquid fuels with high quality. Heterogeneous catalysts with high activity in deoxygenation and denitrogenation are preferable for the conversion of algae oil to high-grade liquid fuel. The paper summarized the influence of reaction parameters and reaction routes for the catalytic conversion process of algae from critical literature. The development of new catalysts, conversion conditions, and efficiency indicators (yields and selectivity) from different literature are presented and compared. The future prospect and challenges in general utilization of algae are also proposed.
