Fossil Fuel Energy

Although biogas is clean and environmentally friendly, its existence is often unsustainable, especially in rural area. Consumption of fossil fuel energy still dominates because cheaper, higher in energy efficiency and ready to use than biogas. One of the efforts to make biogas can compete with fossil fuel energy is by increasing calorific value. Reduction of carbon dioxide by adsorption enhances the calorific value that evidenced by methane enrichment. In this study, we investigated the effect three types of combined adsorbent: pure natural zeolite (Z-Z), zeolite-biochar from chicken manure (Z-B1) and zeolite-modified biochar (Z-B2) on methane content. The result showed that adsorption of biogas using Z-Z, Z-B1 and Z-B2 increased methane level with enhancement of 1,36; 28,92; and 11,27% respectively compared before adsorption. To confirm whether these results were influenced by adsorbent’s character or not as consequence adsorbent characterization have been done in this study.

Adsorbent Materials

The trace amounts of carbon dioxide and hydrogen sulfide in raw biogas lower its calorific value,cause corrosion and make it hard to compress biogas into the cylinder. Raw biogas was obtainedfrom anaerobic digestion of cow dung and market wastes. The gas was stored in tubes or urine bagbefore upgrading. Natural zeolite rocks, maize cobs, steel wire, desulphurizer, and worn-out tyreswere used as the upgrade materials. The composition of biogas was recorded before and afterupgrading using a GP180 portable biogas analyzer from Henan, China. The measured level of rawbiogas was 0.0227% H2S, >20% CO2 and 52-56% CH4. The most efficient upgrade materials werezeolite rocks with upgrade levels of 89–93% methane. The total removal using zeolite wasobserved to be 75% CO2 and 95.34% H2S. The morphological structures of zeolitic rocks accountfor its higher upgrading properties compared to other materials. In addition, the porosity in theserocks mean that CO2 and H2S were adsorbed resulting in high CH4 levels in the upgraded biogas.Other adsorbents showed upgrading properties with removal rates above 70% for both H2S andCO2.

Fossil Fuel Energy

Coal is the most widely available fossil fuel energy resource. This work was carried out to compare the composition, Sulphur content and combustibility of the Nigerian and Nigerien coal samples. Coal samples were obtained from Enugu, Nigeria, Tahuoa and Agadez of Niger Republic. Results indicated that, coal samples from Tahuoa (RS/T) and coal from Agadez (RS/A) have highest percentage of fixed carbon (71.2% and 61.0% for Tohoua and Agadez respectively), while the coal from Enugu (RS/E), Nigeria, have the least percentage (49.2%) which made them to have high fuel ratio enabling them to be more combustible, as determined by the thermal efficiency test. The study revealed that the coal from Niger is of higher grade with ease of combustion and less smoke as found in the combustibility test. Keywords: Coal, Sulphur, fuel ratio, carbon content, combustion and thermal efficiency.
