The adsorbent which selects special carrier and additives is manufactured by a series unique process. At room temperature it is mainly used for removal arsine in liquid hydrocarbon feedstock, such as in naphtha, gasoline, diesel, kerosene, ethylene cracker feedstock. It has the advantage of stable performance, strong adaptability and good mechanical strength, high precision of arsine removal and large arsenide capacity. Its service life is longer than other arsenic –removal adsorbents. It has cost performance price ratio and excellent Comprehensive Performance.
