The patches should look as on the paper, e.g. :

fb-res:2ug-patch a sioc:Item, cs:ChangeSet ;
    sioc:reply_of dbpedia:Leipzig ;
    cs:subjectOfChange dbpedia:Leipzig ;
    foaf:maker <http://aksw.org/NatanaelArndt> ;
    cs:creatorName "Natanael Arndt" ;
    sioc:created_at "2016-01-22T09:55:25.470Z"^^xsd:dateTime ;
    cs:createdDate "2016-01-22T09:55:25.470Z"^^xsd:dateTime ;
    cs:changeReason "Revised Triple ..." ;
    cs:addition [ a rdf:Statement ;
        rdf:subject dbpedia:Leipzig ;
        rdf:predicate ex:propA ;
        rdf:object "Hello" ;
    ] ;
    cs:removal [ a rdf:Statement ;
        rdf:subject dbpedia:Leipzig ;
        rdf:predicate ex:propA ;
        rdf:object "Hey There" ;
    ] .

respectively:

    sioc:reply_of dbpedia:Leipzig ;
    cs:subjectOfChange dbpedia:Leipzig ;
    foaf:maker <http://aksw.org/NatanaelArndt> ;

_:removal a rdf:Statement ;

Basically you only have to use reification in the blank nodes. https://stackoverflow.com/questions/1312741/simple-example-of-reification-in-rdf

With N-Quads blank node usage is done as described in https://www.w3.org/TR/n-quads/#BNodes

When I transform the generated n-quads into turtle I get the structure as described in the paper. I am not able to create trig. Please provide how the following graph should be formated in nquads:

Its actually no issue about the usage of blank nodes but how you express the removals and additions. in N-Triples it should look as follows:

_:addition <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.w3.org/1999/02/22-rdf-syntax-ns#Statement> .
_:addition <http://www.w3.org/1999/02/22-rdf-syntax-ns#subject> <http://dbpedia.org/resource/Leipzig> .
_:addition <http://www.w3.org/1999/02/22-rdf-syntax-ns#predicate> <http://example.org/propA> .
_:addition <http://www.w3.org/1999/02/22-rdf-syntax-ns#object> "Hello" .
_:removal <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://www.w3.org/1999/02/22-rdf-syntax-ns#Statement> .
_:removal <http://www.w3.org/1999/02/22-rdf-syntax-ns#subject> <http://dbpedia.org/resource/Leipzig> .
_:removal <http://www.w3.org/1999/02/22-rdf-syntax-ns#predicate> <http://example.org/propA> .
_:removal <http://www.w3.org/1999/02/22-rdf-syntax-ns#object> "Hey There" .

rather then

_:addition <http://example.org/propA> "Hello" .
_:removal <http://example.org/propA> "Hey There" .

OK I got it. Please review. An example:

Seems correct
