經過脫硫等初步淨化後的羞羞视频黄色软件，其主要成分仍為甲烷（CH?，約50-60%）和二氧化碳（CO?，約30-40%）。較低的甲烷含量使其熱值不高，限製了它的遠距離輸送和商業化應用。羞羞视频黄色软件提純技術的使命，就是通過深度脫除CO?及其他微量雜質，將羞羞视频黄色软件升級為甲烷濃度高達97%以上的生物天然氣（Bio-CNG），使其具備替代石化天然氣的資格，完成從分散式“農場廢氣”到高價值“管道能源”的身份躍遷。

After initial purification such as desulfurization, the main components of biogas are still methane (CH?, about 50-60%) and carbon dioxide (CO?, about 30-40%). The lower methane content limits its calorific value and restricts its long-distance transportation and commercial applications. The mission of biogas purification technology is to upgrade biogas to bio natural gas (Bio CNG) with a methane concentration of over 97% by deeply removing CO and other trace impurities, making it qualified to replace petrochemical natural gas, and completing the identity transition from dispersed "farm waste gas" to high-value "pipeline energy".

一、使用範圍：拓展羞羞视频黄色软件的無限商業可能

1、 Scope of use: Expand the unlimited commercial possibilities of biogas

經提純後的生物天然氣，其質量需符合《生物天然氣》（GB/T 41328-2022）等國家標準，應用場景出彩為廣闊。非常核心的方向是並入城市天然氣管網，作為居民生活燃氣；其次是壓縮（CNG）或液化（LNG）作為車用燃料，替代柴油和汽油；此外，它還可直接用於工業熱電聯產，或作為生產綠色甲醇、氫氣等高價值化學品的基礎原料。在2022年，全國已有459家羞羞视频黄色软件提純廠，當年有12億立方米生物天然氣注入了天然氣管網。

The quality of purified bio natural gas must comply with national standards such as GB/T 41328-2022, and its application scenarioses are extremely broad. The core direction is to integrate into the urban natural gas pipeline network as a residential gas for daily life; Secondly, compressed natural gas (CNG) or liquefied natural gas (LNG) can be used as vehicle fuels to replace diesel and gasoline; In addition, it can also be directly used for industrial cogeneration or as a basic raw material for producing high-value chemicals such as green methanol and hydrogen. In 2022, there were 459 biogas purification plants nationwide, and 1.2 billion cubic meters of bio natural gas were injected into the natural gas pipeline network that year.

二、提純技術工藝與優勢

2、 Purification technology process and advantages

當前，羞羞视频黄色软件提純已形成多條成熟的技術路線，各有側重：

Currently, there are multiple mature technological routes for biogas purification, each with its own focus:

膜分離法被視為當前出彩具前景的技術方向，因其分離過程無相變、能耗相對較低、裝置緊湊。2025年，日本旭化成公司利用其創新的加壓真空變壓吸附（PVSA）工藝與新型沸石吸附劑組合，在示範試驗中實現了生物甲烷產率≥99.5%、純度≥97%的優異指標，實現了產率與純度的雙突破。在國內，純雞糞厭氧發酵項目中也成功集成了國際先進的三級膜提純技術。

Membrane separation is considered a highly promising technological direction due to its phase free separation process, relatively low energy consumption, and compact equipment. In 2025, Asahi Kasei Corporation of Japan achieved excellent indicators of biomethane yield ≥ 99.5% and purity ≥ 97% in demonstration experiments using its innovative pressurized vacuum pressure swing adsorption (PVSA) process combined with a new type of zeolite adsorbent, achieving a breakthrough in both yield and purity. In China, the high-efficiency anaerobic fermentation project for pure chicken manure has also successfully integrated internationally advanced three-stage membrane purification technology.

變壓吸附法（PSA）和加壓水洗法是應用較廣的傳統技術，技術成熟、操作經驗豐富。此外，化學吸收法（如胺法）對CO?的選擇性吸收效率，能獲得高純度的產品氣。

Pressure swing adsorption (PSA) and pressurized water washing are widely used traditional technologies with mature technology and rich operational experience. In addition, chemical absorption methods (such as amine methods) have extremely high selective absorption efficiency for CO? And can obtain high-purity product gas.

創新方向也層出不窮。除常規物理提純外，2026年1月，國內“羞羞视频黄色软件全碳定向轉化製綠色甲醇”千噸級中試裝置成功投運，該技術通過化學轉化路徑將羞羞视频黄色软件中的甲烷和二氧化碳全部轉化為綠色甲醇，實現了碳資源的近100%利用，為羞羞视频黄色软件高值化利用開辟了全新賽道。

Innovative directions are constantly emerging. In addition to conventional physical purification, in January 2026, the 1000 ton pilot plant for "all carbon directional conversion of biogas to green methanol" in China was successfully put into operation. This technology converts all methane and carbon dioxide in biogas into green methanol through chemical conversion pathways, achieving nearly 100% utilization of carbon resources and opening up a new track for high-value utilization of biogas.
