Pulp and paper chemistry

History[ edit ] Five seminal steps in ancient Chinese papermaking outlined in a woodcut. Pulp for papermaking was produced by macerating mulberry bark as early as the 2nd century in Han dynasty China, where the invention of paper is traditionally attributed to Cai Lun. In addition to mulberry, pulp was also made from bamboo, hibiscus bark, blue sandalwood, straw, and cotton.

Researchers find way to turn sawdust into gasoline November 25, Researchers at KU Leuven's Centre for Surface Chemistry and Catalysis have successfully converted sawdust into building blocks for gasoline. Using a new chemical process, they were able to convert the cellulose in sawdust Engineered softwood could transform pulp, paper and biofuel industries April 21, Scientists today demonstrated the potential for softwoods to process more easily into pulp and paper if engineered to incorporate a key feature of hardwoods.

The finding, published in this week's Proceedings of the National Team develops lignin-based thermoplastic conversion process November 30, Phys.

New process transforms wood, crop waste into valuable chemicals November 3, Scientists today disclosed a new method to convert lignin, a biomass waste product, into simple chemicals. The innovation is an important step toward replacing petroleum-based fuels and chemicals with biorenewable materials, Researchers design trees that make it easier to produce pulp April 3, Researchers have genetically engineered trees that will be easier to break down to produce paper and biofuel, a breakthrough that will mean using fewer chemicals, less energy and creating fewer environmental pollutants.

A molecule from plants and trees could make our roads and roofs 'greener' March 22, Construction crews may someday use a plant molecule called lignin in their asphalt and sealant mixtures to help roads and roofs hold up better under various weather conditions.

It also could make them more environmentally Recommended for you Brilliant iron molecule could provide cheaper solar energy November 30, For the first time, researchers have succeeded in creating an iron molecule that can function both as a photocatalyst to produce fuel and in solar cells to produce electricity.

The results indicate that the iron molecule Bringing MOFs into the industrial light November 30, Researchers from Australia's national science agency, CSIRO, are part of an international collaboration which has made a major breakthrough that could change the way gases, liquids and chemicals are collected and filtered Researchers develop tool for speedy diagnosis of bacterial infections November 29, Using a small and inexpensive biosensor, researchers at UBC Okanagan, in collaboration with the University of Calgary, have built a diagnostic tool that provides health care practitioners almost instant diagnosis of a bacterial High-throughput platform enables activity mapping of emerging cancer drug targets November 28, A powerful new biochemical platform is fueling the study of a family of enzymes that are promising targets for cancer treatment.

Virtual library of 1 million new macrolide scaffolds could help speed drug discovery November 28, Researchers from North Carolina State University have created the largest publicly available virtual library of macrolide scaffolds. The library—called V1M—contains chemical structures and computed properties for 1 millionFrom the largest supplier of paper chemicals to the leading supplier of paper chemistry BASF is the world’s leading supplier of chemicals to the paper and board industry.

Our innovative solutions help papermakers deliver top quality and increase productivity while reducing total cost of operation. Nordic Pulp & Paper Research Journal (NPPRJ) is an international scientific magazine covering science and technology for the areas of wood or bio-mass constituents, pulp and paper and including new fiber-based materials, recovery and by-products from pulping processes, bio-refining and energy issues.

Kraft pulping process is the most used pulping process in the world. In this process lignin goes into the reactions with the cooking liquor chemicals and split into fragment.
