ELECTRICITY GENERATED BY ALTERNATIVE BIOFUEL PRODUCTED FROM AGRICULTURAL WASTE

Abstract

Egypt still depends largely on petrol and diesel to run internal combustion engines with its attendant problems of scarcity, pollution of the environment, and contribution to global warming, and cost. The aim of the current research is the ability to apply the biofuel produced from agriculture waste bioethanol and biogas to generate the electricity by operating the two stroke Gasoline Generator. The bio-ethanol produced from the potato’s wests in 2014, Faculty of agriculture, Kafrelsheikh University was mixed with Gasoline fuel to obtain the three different percentage 0%, 20 % and 50%. As well as the study included that the ability to produce the biogas. The biogas production unit consists of main reactor tank from plastic with capacity 1000 L fixed at ground and the collecting gas tank put into the top of main reactor tank. The gasoline with octane 80 was used as a control fuel at two different throttle fuel positions. The main treatment were the two bioethanol fuel E20 (20 %) and E50 (50%) to test at half and full open throttle valve compared to application of biogas to generate the electricity at full open fuel throttle valve. Bachrach Fylite Insight Plus ® model 374 analyzer is used to measure the exhaust gases. This current research will discuss the potentials, obstacles and necessary framework conditions for the utilization of biogas for small scale electricity generation in Egypt. The results showed that the bioethanol and biogas may able to operate two stroke SI engine. It is clearly that, the electrical energy decreases when the ethanol was added to the Gasoline fuel Oct. Nr. 80 at full and half throttle position. The electrical power for gasoline Oct.Nr.80 fuel was 720 W compared to 680 W, 540 W and 320 W for E20 and E50 bioethanol fuel and biogas respectively at full throttle position. Also the maximum electrical power generated from biogas was 332.6 W for around 57 min operating time/day. The percentage of the CO2 in exhaust gases were 9.1 %, 7.3 %, 5.9 % and 4.2 % for gasoline Oct.Nr.80 fuel, bioethanol E20, E50 and biogas respectively at full throttle position. The biogas may be reducing the exhaust gases emissions of the CO and CO2 compared with the Gasoline fuel and bioethanol E20, E50 blend fuel.
