The conversion of syngas to hydrocarbons via Fischer−Tropsch synthesis (FTS) and to alcohols via higher alcohols synthesis (HAS) are two important chemical reactions that generate liquid fuels. Heterogeneous catalysts supported on carbon have been used in both of these fields. In this review, we first describe the features and surface properties of several shaped carbon materials, including carbon black, activated carbon, carbon nanotubes, carbon nanofibers, carbon spheres, ordered mesoporous carbon, graphene, and diamond. In particular, the microscopic structures of these shaped carbons are compared to differentiate the specific characteristics of different shaped carbons. Then we review the recent advances in the study of heterogeneous catalysts supported on these shaped carbon materials used for FTS and HAS from syngas in the past two decades. Various catalyst parameters, such as promoters, stability, autoreduction, pore structure, carbon morphology, and metal particle size, etc., are discussed and summarized.

“…Therefore, acid transesterification biomass may prove to be an important technology for the production of biodiesel, not only from microalgae oils. Recently, hydroesterification has been viewed as an alternative to microalgae biodiesel production due to its promising results to obtain fatty acids with above 80% recovery from the hydrolysis of wet biomass [83] [84].…”

Global increases in atmospheric CO 2 and climate change are drawing considerable attention to identify sources of energy with lower environmental impact than those currently in use. Biodiesel production from microalgae lipids can, in the future, occupy a prominent place in energy generation because it represents a sustainable alternative to petroleum-based fuels. Several species of microalgae produce large amounts of lipids per biomass unit. Triacylglycerol is the fatty acid used for biodiesel production and the main source of energy reserves in microalgae. The current literature indicates that nutrient limitations can lead to triacylglycerol accumulation in different species of microalgae. Further efforts in microalgae screening for biodiesel production are needed to discover a native microalgae that will be feasible for biodiesel production in terms of biomass productivity and oil. This revision focuses in the biotechnological potential and viability of biodiesel production from microalgae. Brazil is located in a tropical region with high light rates and adequate average temperatures for the growth of microalgae. The wide availability of bodies of water and land will allow the country to produce renewable energy from microalgae.
