Assignment of project management assistance in technical, administrative, legal and financial matters in the framework of the realization of a biogas methanation unit and composting of digestates in aspach-michelbach
The catalyst was originally developed at the University of Chicago and the basic methanation system was designed by Electrochaea and demonstrated in Europe.
BASF has synthesized a catalyst for the generation of SNG through the methanation of syngas from either biomass gasification or coal gasification.
After 60 minutes, using 1 mL syringes, the internal atmosphere of the container was sampled and C[O.sub.2] concentrations were measured, using a Varian[R] CP-3800 gas chromatograph (Palo Alto, CA, USA), equipped with a 3m Porapak N[R] column, methanation reactor and flame ionization detector.
There are emerging techniques that are not currently ready for widespread deployment but have the potential to increase the energy recovered from waste in the future: bubbling fluidized bed gasifier, plasma gasification, combined pyrolysis and gasification, gasification with syngas methanation and conversion to biomethane, among others.
The future projects will be in the industrial water recycling and treatment sector and include building an ammonia production unit and a methanation unit.
The inefficiency of waste management also causes environmental deterioration because of the natural methanation process from biomass dumping [1].

(2001) found out that the optimum calcium concentration for the methanation of acetic acid is 200 mg [Ca.sup.+2] [l.sup.-1] with the limit ranging from 2000 to 5000 mg [Ca.sup.+2] [l.sup.-1].
Then by increasing the coal content further, CO is produced and consumed by Boudouard and methanation reactions respectively [38].
However, this is difficult because, besides the main deoxygenation reactions, other gaseous reactions, such as water gas shift or methanation, could take place on the investigated catalyst.
