Ethanol Production Process - an overview | ScienceDirect

The ethanol production process consists of four main stages:. Pretreatment: The lignocellulosic material, which mainly consists of cellulose hemicellulose and lignin, is treated with dilute acid at high temperatures and pressure to degrade the lignin and to convert the hemicellulose into xylose and by-products (e.g furfural, HMF and organic acids) (Esteghlalian et al., 1997; Nigam et al., 2011).

Energies | Free Full-Text | Cost and Environmental

While the production costs and logistical benefits of biomass pelleting have been widely discussed in the literature, the downstream economic and environmental benefits of processing pelleted biomass have been largely neglected. To investigate those benefits, we performed a comparative techno-economic analysis and life cycle assessment of producing ethanol using loose and pelleted forms of

Miscanthus x giganteus - Wikipedia

Miscanthus × giganteus, the giant miscanthus, is a sterile hybrid of Miscanthus sinensis and Miscanthus sacchariflorus. It is a perennial grass with bamboo-like stems that can grow to heights of more than 4 metres (13 ft) in one season (from the third season onwards). Just like Pennisetum purpureum, Arundo donax and Saccharum ravennae, it is also called elephant grass.

Thermal Cracking - an overview | ScienceDirect Topics

The Eureka process is a thermal cracking process to produce a cracked oil and aromatic residuum from heavy residual materials (Aiba et al., 1981; Parkash, 2003; Gary et al., 2007; Speight, 2014, 2017; Hsu and Robinson, 2017).In this process (Fig. 5.6) the feedstock, usually a vacuum residuum, is fed to the preheater and then enters the bottom of the fractionator, where it is mixed with the

Briquette - Wikipedia

A briquette (French: ; also spelled briquet) is a compressed block of coal dust or other combustible biomass material (e.g. charcoal, sawdust, wood chips, peat, or paper) used for fuel and kindling to start a fire.The term derives from the French word brique, meaning brick

Bioenergy: sustainable renewable energy

Biomass conversion pathways include thermal, biochemical or mechanical either alone or in combination. Biomass can be converted to energy via a range of technologies from simple solid wood combustion heaters, to boilers and biodigesters which in turn produce gas for process steam for heat or for powering engines and turbines.

Rankine cycle - Wikipedia

Description. The Rankine cycle closely describes the process by which steam engines commonly found in thermal power generation plants harness the thermal energy of a fuel or other heat source to generate electricity. Possible heat sources include combustion of fossil fuels such as coal, natural gas, or oil, renewable fuels like biomass or ethanol, nuclear fission, and concentrated solar power.

Pyrolysis: A Sustainable Way to Generate Energy from Waste

Jul 05, 2017 · Biomass melting is done by pressing mechanically the biomass against the wall of a heated reactor and as the melted sample is moved, the pyrolysis vapours evaporate as oil. While this reactor allows for a large biomass particle size (up to 20 mm), the materials does not require excessive grinding . However, the configuration of the reactor is a
