Fuels from Non-Cereal Crops

Agricnltnral residnes snch as straws, nnt shells, frait shells, fmit seeds, plant stalks, green leaves and molasses are potential renewable energy resonrces. 

The following describes the process of mannre and straw mixtnre digestion. For the first 3 days, the methane yield is almost 0% and carbon dioxide generation is roughly 100%. In this period, digestion occius as aerobic fermentation to carbon 

Anaerobic digestion yields of the slurries are given in Table 2.5. Due to the higher proportion of lipids in manure, the methane production is higher than in wheat straw. The total amounts of lipid and protein, in particular, are lower in straw than in manure and thus the theoretical methane yield is significantly lower in wheat straw than in manure (Table 2.5). The average methane yields of manure and wheat straw were 14.7% and 10.4% of volatile solids, respectively (Demirbas and Ozturk, 2004).

When the pyrolysis temperature increased the biochar yield decreased. The biochar yield increased with increasing particle size of the sample. The yield of biooil from pyrolysis of the samples increased with temperature. Anaerobic biogas prodnction is an effective process for conversion of a broad variety of agricultural biomass to methane to snbstitnte natnral gas and medinm calorific valne gases.
