Biogas is a mixed gas, mainly composed of methane [CH4], and the rest are carbon dioxide [CO2], oxygen [O2], nitrogen [N2], and hydrogen sulfide [H2S]. The methane content is about 60% -80%, and the physical and chemical properties of biogas are mainly composed of methane. Methane is a colorless and odorless gas, with a molecular weight of 16.04. At the standard state of OOC, 101325Pa, the relative density of methane to air is 0.5548, The calorific value of methane is 35.9M/m3, and the low calorific value of biogas is 20-25MJ/m3.

硫化氢的危害性：沼气内的硫化氢,不但腐蚀管道及设备，更重要的是使人硫化氢中毒。给人们的身体健康造成危害，严重时可以致人死亡。

The harm of hydrogen sulfide: Hydrogen sulfide in biogas not only corrodes pipelines and equipment, but more importantly, causes hydrogen sulfide poisoning in humans. Causing harm to people's physical health, and in severe cases, it can lead to death.

根据科学性物理性研制出了ZDE-01、ZDE-02、ZDE-03型常温氧化铁沼气精脱硫剂。主要是三氧气化二铁(Fe203]，含量为40％，并添加多种助剂，根据尖端科技技术制成，是一种适应性强的新型高效沼气精脱硫剂．具有硫容量大、脱硫精度高、适应性强等特点，是目前国内脱硫剂市场优质产品，长期以来深受新老用户的青睐。

ZDE-01, ZDE-02, and ZDE-03 room temperature iron oxide biogas desulfurization agents have been developed based on scientific and physical properties. Mainly iron trioxide (Fe203), with a content of 40% and various additives added, made based on cutting-edge technology, is a new and highly efficient biogas desulfurization agent with strong adaptability. It has the characteristics of large sulfur capacity, high desulfurization accuracy, and strong adaptability. It is currently a high-quality product in the domestic desulfurization agent market and has long been favored by new and old users.

综上所述，从脱硫塔或脱硫器工艺上需要的装填量要求，还应考虑选用优质的脱硫剂．根据脱硫剂的再生反应原理,在设计脱硫塔或脱硫器时可考虑重复多次自然再生设计，方便用户使用时能实现重复多次再生，可延长l／2的使用时间，从而降低了成本，大大增加了脱硫剂的使用时间，考虑沼气特殊的气质，在提高脱硫效率的同时，又降低了成本．如果使用澳门永利网最老登陆入口的煤气脱硫剂，可在贵公司脱硫工艺的基础上，从一般的脱硫剂25％的硫容可增大到35％，从而延长了1／2的使用时间，大大的降低了脱硫成本，能全面满足贵公司的脱硫工艺要求．

In summary, in terms of the required loading requirements for the desulfurization tower or desulfurization device process, high-quality desulfurization agents should also be considered. According to the regeneration reaction principle of desulfurization agents, when designing the desulfurization tower or desulfurization device, the design of repeated natural regeneration can be considered, which is convenient for users to achieve repeated regeneration and can extend the usage time by 1/2, thereby reducing costs and greatly increasing the usage time of desulfurization agents, Considering the unique temperament of biogas, while improving desulfurization efficiency, it also reduces costs. If we use our company's coal gas desulfurization agent, the sulfur capacity of the general desulfurization agent can be increased from 25% to 35% based on your company's desulfurization process, thereby extending the usage time by 1/2, greatly reducing desulfurization costs, and fully meeting your company's desulfurization process requirements

优质常温氧化铁脱硫剂的选择:

Selection of high-quality room temperature iron oxide desulfurization agent:

各生产厂家的企业标准大不相同，产品性能差异很大，许多生产厂家产品远不能达到行业要求，所以用户在选择脱硫剂时很关键，由于各生产厂家产品三氧化二铁有效含量不同，脱硫剂的活性差异也很大，而脱硫精度相差甚远，增加三氧化二铁含量可提高脱硫精度，脱硫剂要求硫容高，大于25—35％之间，脱硫精度

The enterprise standards of various manufacturers vary greatly, and the performance of their products varies greatly. Many manufacturers' products are far from meeting industry requirements, so it is crucial for users to choose desulfurizers. Due to the different effective content of iron oxide in their products, the activity of desulfurizers varies greatly, and the desulfurization accuracy varies greatly. Increasing the content of iron oxide can improve the desulfurization accuracy, and desulfurizers require high sulfur capacity, Greater than 25-35%, desulfurization accuracy

耐水性强，磨耗率低，强度适中，孔容大，脱硫剂的还原再生效果要强，一般的脱硫剂再生后活性衰减厉害，再生后基本无活性，而较好的脱硫剂可重复再生数次，再生还原时间快等优点．

Strong water resistance, low wear rate, moderate strength, large pore volume, and strong reduction and regeneration effect of desulfurizers. Generally, desulfurizers have a significant decrease in activity after regeneration, and have little activity after regeneration. However, better desulfurizers can be regenerated several times and have advantages such as fast regeneration and reduction time
