Methane gas

In this study, SrTiO3 catalyst was prepared by sol-gel method and CuOZnO by co-precipitation for oxidative coupling of methane (OCM). The XRDresults showed a stable phase structure and high crystallinity with both samples. NH3-TPD recorded weak acid centers on SrTiO3, leading to coke formation on the impact surface. H2-TPR and O2 - TPD express the redox of CuO-ZnO, resulting in a deep oxidation product of CO2.

Landfill gas from a source of green energy, clean, renewable and can be used to create electricity, or used in the energy industry. This paper reviews the potential energy recovery landfill gas from municipal solid waste, to reducing methane emissions in particular, and reduced greenhouse gas emissions in general. In addition, this paper provides an assessment using the model of methane generated from landfill municipal solid waste and generate energy potential of gas recovered. In particular, this paper uses a life cycle assessment methods ......

Băng cháy là một thứ ở dạng rắn, hình thành từ khí thiên nhiên và nước, ở dưới điều kiện áp suất cao (trên 30 atm) và nhiệt độ thấp (dưới 0 độ C), có tên khoa học là Natural hydrate, hoặc Gas Hydrate. Khi hàm lượng methane vượt quá 75% thành phần của Gas Hydrate thì nó thường được gọi là methane hydrate. Chỉ cần nâng nhiệt độ hoặc giảm áp lực là băng cháy sẽ phân giải: 1m3 chất này khi phân giải cho ra 164 m3 khí methane và 0,8 m3 nước, đủ thấy năng lượng mà...
