The Impact of a Mild Sub-Critical Hydrothermal Carbonization Pretreatment on <i>Umbila</i> Wood. A Mass and Energy Balance Perspective

Cuvilas, Carlos Alberto; Kantarelis, Efthymios; Yang, … - In: Energies 8 (2015) 3, pp. 2165-2175

Over the last years, the pretreatment of biomass as a source of energy has become one of the most important steps of biomass conversion. In this work the effect of a mild subcritical hydrothermal carbonization of a tropical woody biomass was studied. Results indicate considerable change in...

Recent Advances in Direct Coal Liquefaction

Shui, Hengfu; Cai, Zhenyi; Xu, Chunbao - In: Energies 3 (2010) 2, pp. 155-170

The growing demand for petroleum, accompanied by the declining petroleum reserves and the concerns over energy security, has intensified the interest in direct coal liquefaction (DCL), particularly in countries such as China which is rich in coal resources, but short of petroleum. In addition to...

A review of biomass co-firing in North America

Agbor, Ezinwa; Zhang, Xiaolei; Kumar, Amit - In: Renewable and Sustainable Energy Reviews 40 (2014) C, pp. 930-943

Biomass fuels have long been accepted as useful renewable energy sources, especially in mitigating greenhouse gases (GHG), nitrogen oxides, and sulfur oxide emissions. Biomass fuel is carbon neutral and is usually low in both nitrogen and sulfur. For the past decade, various forms of biomass...

A critical review on anaerobic co-digestion achievements between 2010 and 2013

Mata-Alvarez, J.; Dosta, J.; Romero-Güiza, M.S.; Fonoll, X. - In: Renewable and Sustainable Energy Reviews 36 (2014) C, pp. 412-427

Anaerobic digestion is a commercial reality for several kinds of waste. Nonetheless, anaerobic digestion of single substrates presents some drawbacks linked to substrate characteristics. Anaerobic co-digestion, the simultaneous digestion of two or more substrates, is a feasible option to...

Particle size reduction optimization of Laminaria spp. biomass for enhanced methane production

Tedesco, Silvia; Mac Lochlainn, Dubhaltach; Olabi, … - In: Energy 76 (2014) C, pp. 857-862

Recent studies have reported improved biogas and methane yield from marine biomass when the particle size is mechanically reduced and the specific surface area available to enzymes is increased prior to anaerobic incubation. Although the advantage of reducing the particle size has been...

Using an efficient fermenting yeast enhances ethanol production from unfiltered wheat bran hydrolysates

Favaro, Lorenzo; Basaglia, Marina; Zyl, Willem H. van; … - In: Applied Energy 102 (2013) C, pp. 170-178

Wheat bran, an abundant residue of the flour milling industry, is a promising feedstock for bioethanol production. The first objective of the present study was to define the optimised hydrolysis conditions for wheat bran that gave both high sugars concentration and little or no inhibitors...
