Definitions

  • This invention relates to a process for production of pulp for making paper and other fibrous products, and to bioenergy applications from grassland cropping systems.
  • a "grassland cropping system” is defined as a method of growing and producing forage grasses and other members of the grass family, such as bamboo and giant reed (Arundo donax) and grain crops, and harvesting, handling, processing, storing and transporting them to a pulp mill or energy plant.
  • the invention further relates to a process that is based on annual and perennial grasses that are already widely grown throughout the world, primarily to produce grain and/or forage for livestock.. Therefore, this invention offers the distinct advantage of diversifying use of these herbaceous crops by allowing them to be grown specifically for production of pulp and energy, in addition to their typical use for production of forage and/or grain and other purposes.
  • grasses are incompatible with wood chip feeding systems in pulp mills which process wood chips (which amount to 99.7% of the US pulping capacity); [0009] 6) grasses have a low bulk density, and therefore are expensive to transport; [0010] 7) grasses often do not density easily by means of pelletizing and cubing, and these densification processes are assumed to be too expensive; [0011] 8) grasses are perceived to have higher silica contents (up to 14%) than wood, and this causes difficulty with chemical recovery in many pulping processes; [0012] 9) expense is incurred in planting grass crops, and many growers are not willing to spend the money needed for this operation; [0013] 10) with perennial grasses it often takes 3 years to reach full yield, and growers are often not willing to wait this long to receive a full return on their investment.
  • grasses are more difficult and expensive to handle, load, transport and offload than wood chips and coal are, because grasses are usually packaged in big round bales which need to be picked up, loaded and unloaded individually instead of using conveyer belt systems, as for wood chips and coal.
  • Most of the world's energy comes from fossil fuels: oil, coal and natural gas.
  • biomass can be used in many processes to produce energy, including biofuels (such as ethanol and methanol), gases (such as syngas from gasification, and hydrogen), and electricity (such as co-firing biomass with coal, or running steam or gas turbines with gas generated from a biomass gasifier), but biomass is currently used in energy applications only when it is a no-cost or low-cost byproduct of another industry, and these applications have been implemented mainly with woody biomass.
  • biofuels such as ethanol and methanol
  • gases such as syngas from gasification, and hydrogen
  • electricity such as co-firing biomass with coal, or running steam or gas turbines with gas generated from a biomass gasifier
  • grasses have a high proportion of leaves, which are considered to have a lower energy content than stems and wood;
  • grasses are low in bulk density, and therefore expensive to transport; [ [00002244]] 4 4)) grasses are incompatible with coal feeding systems (they bridge and cause blockages);
  • grasses need to be dried after harvesting and this depends on the weather which is unsuitable in certain seasons of the year; [0030] 10) grasses have annual growth cycles, and because of this, as well as point 12 above, they cannot be harvested continuously throughout the year, as are trees; [0031] 11) due to points 9 and 10 above, there is a greater need to store grass material after harvesting than there is for wood;
  • the present invention comprises a method of producing a fibrous pulp comprising harvesting and drying a grass plant to produce harvested material; collecting said harvested material; size reduction of said harvested material; densification of said harvested material; and transporting said harvested material to a pulp mill to produce fibrous pulp or to an energy plant to produce energy.
  • Some objectives of this invention are: [0037] 1) to provide a process for using grassland cropping systems which include annual and perennial grasses typically used for production of forage or grain, to produce pulp and energy;
  • Densification is any process by which the bulk density (weight per unit volume) of a specified material is increased.
  • Fibrous pulp is pulp comprised of fibrous plant material.
  • the fibers usually consist mainly of cellulose, but also include some hemicellulose, lignin and other components of plant tissue.
  • Size reduction refers to reduction in average particle size of particulate material as measured by the amount of material that passes through screens with different mesh sizes; e.g., half inch, quarter inch, one eighth inch, etc. For example, "long hay" (unchopped) will not pass through a screen with a mesh size of one inch, but after chopping with a forage chopper, or grinding with a tub grinder, most of the chopped material will pass through a one-inch mesh screen.
  • Syngas is a mixture of gases comprising primarily of carbon monoxide and hydrogen.
  • the invention provides a process for production of pulp and energy by means of grassland cropping systems which include perennial and annual grasses that are either temperate or tropical in nature.
  • grassland cropping systems which include perennial and annual grasses that are either temperate or tropical in nature.
  • the process involves the following steps:
  • grass species selection including annual or perennial grasses that are either tropical or temperate in nature, to be grown alone, in rotation on the same land, or in a mixture;
  • the species used in the grassland cropping systems should preferably include one or more from the following list: Common Name Scientific Name
  • Harvesting and drying can be done with regular sickle bar or disc mowers, mower conditioners, or even by hand, and harvested material can be air dried, or dried artificially.
  • Harvested material can be collected with a baler or a forage chopper.
  • STEP 4 Size Reduction
  • Size reduction is achieved by chopping with a forage chopper, tub grinding, or milling/pulverizing with any of several milling/pulverizing processes.
  • Densification is achieved by baling, pelletizing, cubing, or constructing compressed grass modules, such as with a cotton module builder.
  • the material will be transported by road (truck), rail, barge or ship.
  • the material may be processed further, such as co-milling grass cubes with coal, and fed into pulp mills or energy plants.
