Biogas upgrading to syngas by combined reforming using Ni/CeO2–Al2O3 with bimodal pore structure

نویسندگان

چکیده

Ni/CeO2–Al2O3 with bimodal porous structure and two different CeO2 concentrations (low: 5 wt% high: 15 wt%) were prepared by the refluxed co-precipitation method characterized N2 physisorption, XRD, TPR, H2-TPD, CO2-TPD. Catalysts tested in combined steam dry reforming of methane (CSDRM) at atmospheric pressure, 600°C–700 °C CH4: CO2: H2O = 1: 0.48: 0.8, order to prepare synthesis gas H2:CO ratio 2:1. The catalytic activity decreases increasing ceria content, best catalyst being Ni/CeO2(5 wt%)-Al2O3. good obtained for wt%)-Al2O3 is a consequence more intimate contact alumina, providing higher metal-support interaction, but also dimensions larger pores which contribute better targeting reagents sites. In used catalysts, presence preserved decreased carbon deposition ∼70%.

Review on Innovative Catalytic Reforming of Natural Gas to Syngas

Decreasing supplies of high quality crude oil and increasing demand for high quality distillates have motivated the interest in converting natural gas to liquid fuels, especially with the present boom in natural gas proven reserves. Nevertheless, one major issue is the curtailment of costs incurred in producing synthesis gas from natural gas, which account for approximately 60% of the costs use...

Selected Methods of Advanced Biogas Upgrading

The upgrading of biogas for the production of biomethane to be injected to the natural gas grid has gained significant importance in recent years. It is often considered to be superior to the production of electricity and district heat with internal combustion engines mainly because of better energy utilisation, higher flexibility and beneficial economic prospects. Biogas upgrading is commonly ...

3. Upgrading Dairy Biogas to Biomethane and Other Fuels

Dairy biogas can be combusted to generate electricity and/or heat. This report, however, focuses on alternate uses of biogas including the upgrading of biogas to biomethane, a product equivalent to natural gas or other higher-grade fuels. Biomethane, which typically contains more than 95% CH (with the remainder as CO 4 2), has no technical barrier to being used interchangeably with natural gas,...
