CO. 2. in the purified biogas should be less than 3% [11]. Biogas purification is required as biogas produced from anaerobic digestion process contains some traces such as carbon dioxide (CO2) and hydrogen sulfide (H2S) which lowered the calorific value. Biogas can also be upgraded, which is essentially the removal of CO2, to produce Biomethane (also known as Renewable Natural Gas) which is equivalent to conventional natural gas and can be injected into the gas grid or used as a vehicle fuel (CNG) Nowadays, various techniques are used for CO2 removal from biogas. Among the most commonly used technologies are adsorption, absorption, cryogenic separation, and membrane separation. Percentage removal of hydrogen sulfide was determined every day.

The presence of CO 2 and H 2 S may affect the performance of biogas. Hence, its removal before its use is crucial to improving the quality of biogas. In this work, a method to purify both gasses, CO 2 and H 2 S were employed by using a sodium hydroxide solutions (NaOH). The project has focus on the development and production of zeolite based membranes, which can be used for cleaning of biogas. Biogas produced in an anaerobe biogas reactor contains 25 to 45 % carbon dioxide. The CO2 is undesirable, if the gas is going to be distributed for long distances.
