By 1900 sulfite pulping had become the dominant means of producing wood pulp, surpassing mechanical pulping methods. The competing chemical pulping process, the sulfate or kraft process was developed by Carl F. Dahl in 1879 and the first kraft mill started (in Sweden) in 1890. [ 3 ]
The process was invented by Theodor Kleinert in 1968 [1] as an environmentally benign alternative to kraft pulping. Organosolv has several advantages when compared to other popular methods such as kraft or sulfite pulping. In particular, the ability to obtain relatively high quality lignin adds value to a process stream otherwise considered as ...
The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibres, the main component of paper. The kraft process involves treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na 2 S), known as white ...

Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. [2] Sulfonated lignin (SL) refers to other forms of lignin by-product, such as those derived from the much more popular Kraft process , that have been processed to add sulfonic acid groups.
Fried chicken, brownies from a box and stir-fried veggies—very different foods that, nevertheless, share a common ingredient: vegetable oil. Its omnipresence might suggest otherwise, but don’t ...
Pulp mills have used black liquor as an energy source since at least the 1930s. [8] Most kraft pulp mills use recovery boilers to recover and burn much of the black liquor they produce, generating steam and recovering the cooking chemicals (sodium hydroxide and sodium sulfide used to separate lignin from the cellulose fibres needed for ...
