Effect of Ni/Al₂O₃-SiO₂and Ni/Al₂O₃-SiO₂with K₂O Promoter Catalysts on H₂, CO and CH₄Concentration by CO₂Gasification ofRosa MultifloraBiomass

Abstract

-The thermal behaviour of the Rosa mutiflora biomass by thermogravimetric analysis was studied at heating rate 3 K min À 1 from ambient temperature to 950°C. TGA tests were performed in high purity carbon dioxide (99 998%) with a flow rate 200 ml/min and 100 mg of sample, milled and sieved to a particle size below 250 mm. Moreover, yields of gasification products such as

Comprehensive study on the amount of CO2 absorbed by vegetation: A case study in Ho Chi Minh city, Vietnam

“…The increase in the concentration of CO 2 in the atmosphere is the cause of the problem of climate change because the earth cannot absorb all the CO 2 and other greenhouse gases [1][2][3][4][5]. According to the World Meteorological Organization's (WMO) Greenhouse Gas Report, CO 2 emissions from 2015 to 2016 increased sharply from 400 ppm to 403.3 ppm.…”

Advancements in renewable energy sources (solar and geothermal): A brief review

“…Motivated by environmental imperatives and the need for energy security, governments, industries, and research institutions globally have intensified efforts to explore and enhance the potential of renewable energy technologies. The quest for sustainable energy solutions has led to remarkable strides in the development of solar [3,4], wind [5], hydropower [6][7][8][9][10], geothermal [11][12][13], and biomass [14][15][16][17][18][19][20] technologies. These advancements not only promise cleaner energy but also herald economic opportunities and increased energy independence for nations.…”
