Card 1Biofuels

What are biofuels?

Answer

Biofuels are fuels produced from biological products, including living organisms or waste from biological products such as landfills and recycled vegetable oil. Common examples include biodiesel, bioa…

Card 2जैव ईंधन

जैव ईंधन क्या है?

Answer

जैव ईंधन (Biofuel) जैविक उत्पादों से निर्मित ईंधन होते हैं, जिनमें जीवित जीव या जैविक उत्पादों से निकला कचरा जैसे कि लैंडफिल और पुनश्चक्रित वनस्पति तेल शामिल हैं। सामान्य उदाहरणों में बायोडीजल, बायोअल…

Card 3बायोडीजल

बायोडीजल कैसे बनाया जाता है और इंजन में इसका मुख्य लाभ क्या है?

Answer

बायोडीजल पशु वसा और वनस्पति तेल जैसे कच्चे माल से ट्रांस-एस्टरीफिकेशन द्वारा बनाया जाता है। इसमें जीवाश्म ईंधन की तुलना में अधिक हाइड्रोजन और ऑक्सीजन और कम कार्बन होता है, इसलिए दहन में सुधार होता है।…

Card 4Biodiesel

How is biodiesel produced, and what is its main advantage in engines?

Answer

Biodiesel is produced from raw materials such as animal fats and vegetable oils by trans-esterification. It contains higher hydrogen and oxygen and less carbon than fossil fuels, so combustion is impr…

Card 5Biodiesel

Why is biodiesel considered cleaner than fossil diesel?

Answer

Biodiesel has higher hydrogen and oxygen content and lower carbon content than fossil fuels. This improves combustion and reduces particulate emissions from unburnt carbon.

Card 6बायोडीजल

बायोडीजल को जीवाश्म डीजल की तुलना में स्वच्छ क्यों माना जाता है?

Answer

बायोडीजल में जीवाश्म ईंधन की तुलना में हाइड्रोजन और ऑक्सीजन की मात्रा अधिक और कार्बन की मात्रा कम होती है। इससे दहन में सुधार होता है और बिना जले कार्बन से होने वाले कण उत्सर्जन में कमी आती है।…

Card 7बायोअल्कोहल

बायोअल्कोहल क्या है, और इसके उत्पादन के मुख्य चरण क्या हैं?

Answer

जैव-ऐल्कोहल (Bioalcohol) जैसे कि जैव-इथानॉल (bioethanol) का उत्पादन गेहूँ, मक्का, गन्ना, गुड़, चुकंदर, आलू और फलों के अपशिष्ट जैसे स्रोतों से किया जाता है। इसके उत्पादन में संग्रहित स्टार्च या सेलूलोज…

Card 8Bioalcohol

What is bioalcohol, and what are the main steps in its production?

Answer

Bioalcohol, such as bioethanol, is produced from sources like wheat, corn, sugarcane, molasses, sugar beets, potato, and fruit waste. Its production involves release of sugars from stored starch or ce…
