Abstract
A method for improving a biogas production is provided in which an organic substrate is pretreated by various methods. In particular, the method includes a combination of a magnetic and an enzymatic pretreatment of the substrate with an attractive specific energy gain. The application of a magnetic field induces changes in biological systems.
Claims17
A method to produce biogas from organic substrates comprising:
- providing an organic substrate;
- mixing the organic substrate with an enzyme to form an enzyme-substrate complex;
- exposing the enzyme-substrate complex to an induced magnetic field as magnetic pretreatment, wherein the magnetic pretreatment comprises
- (i) providing the magnetic field;
- and
- (ii) influencing the enzyme-substrate complex by the magnetic field for a time t3, wherein the induced magnetic field is provided by solenoid coil with direct current, wherein the enzyme-substrate complex is influenced by the magnetic field for a time t3, wherein t3 is in a range of 2-6 h and the magnetic field has a magnetic flux density of a range smaller than 1 mT;
- exposing said magnetically treated enzyme-substrate complex to a first temperature T1 for a first time t1 in an incubator, wherein the time t1 is in a range of 10 to 56 h and temperature T1 is between 35° C.-60° C.;
- and
- initiating an anaerobe digestion.
