    Abstract

    Selection of producer gas from biomass is the right choice because it has a high efficiency in the conversion of biomass into energy in the gasification process. Coconut shell is biomass that can be used as feedstock for gasification producer gas produced has a composition of 25% CO, 12% H2, 1.5% CH4, 10% CO2 and N2 51.5%. If the gasification process connected with the dieselgenerator, 1.2 to 2.0 kg / h of biomass can generate 1 kW of electricity. Assuming a specific consumption of raw materials by 2 kg / kWh, then the process of gasification of coconut shell with a capacity of 24 kg feed / hour can produce about 12 kW of electricity. With this capacity can be used for the needs of a group of people (about 20 families) and MSME (Micro, Small and Medium Enterprises). Making tools gasification developed into a more simplified system in the form of portable for easy removal gasification device from one place to another place. The series of portable gasification unit consists of the reactor and a series of producer gas purification unit. Producer gas generated from the gasifier reactor needs to be purified by a series of purification unit consisting of a cyclone, wet scrubber and filter. Producer gas purification carried out to meyesuaikan conditions to be eligible producer gas into the engine generator, namely solids and tar content of <50 mg / Nm3 and a temperature of about 40oC. In operation, it takes two wet scrubber, vortex blower with 2 power HP, and a power blower blow with ¼ HP as the air supply to the gasifier. Making the gasification unit begins a series of fabrication tools, then installation tool such as the installation of piping, electrical and measuring tools. Then, the retrieval of data in the form of bulk density and moisture content, temperature reactor, producer gas temperature in the wet scrubber, cooling water temperature, rate of cooling water, the weight of residual solids, total weight of coconut shell and flame. Then, the calculation of the percentage of residual solids, specific gasification rate (SGR), and the specific water needs. For the determination of the Standard Operational Procedures (SOP) starts from the determination of preparation, start-up, process, shut down and maintenance. After conducting experiments on the specified SOP and perform calculations, the rate of consumption of raw materials 5.620 kg / h - 13.590 kg.jam, specific water needs 25 L / kg of raw material - 55 L / kg of raw material, the remaining 18.52% solids results - 38.03% and the long time required for the formation of coal is 60 minutes - 140 minutes.
