TL;DR: In this paper, the most important factors that determine the structure of high metal content catalysts are discussed with particular reference to the copper, nickel, and iron-based catalysts used in substitute natural gas (SNG) and ammonia production.
Abstract: Publisher Summary High metal content catalysts—such as steam reforming, water gas shift, and methanation—are frequently prepared by using precipitation from aqueous solution as a key stage in forming a high area well dispersed metal plus support structure. This chapter presents an analysis of the most important factors that determine this structure with particular reference to the copper, nickel, and iron-based catalysts used in substitute natural gas (SNG) and ammonia production. The chief feature of good industrial catalysts in this field is not so much that they catalyze the correct reactions with adequate degree of selectivity but rather that they have high activity and long life. The chapter discusses the essential quantitative effects of the various stages in catalyst preparation on the metal surface area and strength of the catalyst in use. In addition to high stabilized metal surface area and mechanical strength, the reduced catalyst must have adequate porosity to enable diffusional access for the reagents and egress for the products.

TL;DR: In this paper, a method for producing substitute natural gas (SNG) which is supplied into a downstream pipeline system, at the feeding pressure and in an energy efficient manner, is presented.
Abstract: The invention relates to a method for producing substitute natural gas (SNG) which is supplied into a downstream pipeline system, at the feeding pressure and in an energy efficient manner. To this end, a syngas containing carbon monoxide and hydrogen is converted into a methane-rich product gas in a main reaction zone and a post-reaction zone by means of multi-stage catalytic methanation, the target pressure being adjusted by compression before the main reaction zone and/or before or in the post-reaction zone.

TL;DR: The Energy research Centre of the Netherlands (ECN) is developing technology for the production of Substitute Natural Gas (SNG) from biomass as mentioned in this paper, which involves indirect gasification, tar removal, further gas cleaning, methanation and upgrading of the product to natural gas standards.
Abstract: The Energy research Centre of the Netherlands (ECN) is developing technology for the production of Substitute Natural Gas (SNG) from biomass. The technology involves indirect gasification, tar removal, further gas cleaning, methanation and upgrading of the product to natural gas standards. The aim is to reach an energy efficiency of at least 70% from biomass to SNG. Results are presented of tests performed with various catalysts and biomass producer gas at labscale(about 1 Nm3/hr).
