Weldability of Low Carbon Steel
Weldability, is one of the most important properties of steels, is the ability of a material to be formed, joined and fabricated. Low carbon steel is known for its good weldability and mild characteristics. It is often used in automobile components and home applian......
oil shale
Shale Oil
Shale oil is a type of unconventional oil which is produced from sedimentary rocks, primarily from shale. It is considered an important source of domestic energy in a number of countries due to its abundance and relatively low cost of extraction. The process of extraction of shale oil i......
Classification of natural gas
Introduction
Natural gas is typically categorized into several distinct categories based primarily on its origin, production, physical state and composition. Generally speaking, natural gas is divided into three main categories.
Classification
Conventional natural gas sits atop this classificat......
Quartz sandstone
Quartz-sandstone is a sedimentary rock that consists primarily of rounded quartz grains and is one of the most common and important types of sandstone. Quartz-sandstone is formed in a variety of environments, and its formation process begins with the erosion and weathering of other rocks and miner......
reserves of coal-derived gas
Coalbed methane, widely known as CBM, is natural gas extracted from coal seams. The gas consists mainly of methane and is sometimes referred to as coal seam gas or coal-mine methane. This resource is an important alternative energy source in many countries, but its reserves are not always understo......
