Title: Plant hydrocarbon recovery process

Abstract

A process for production and recovery of hydrocarbons from hydrocarbon-containing whole plants in a form suitable for use as chemical feedstocks or as hydrocarbon energy sources which process comprises: (A) pulverizing by grinding or chopping hydrocarbon-containing whole plants selected from the group consisting of euphorbiaceae, apocynaceae, asclepiadaceae, compositae, cactaceae and pinaceae families to a suitable particle size, (B) drying and preheating said particles in a reducing atmosphere under positive pressure (C) passing said particles through a thermal conversion zone containing a reducing atmosphere and with a residence time of 1 second to about 30 minutes at a temperature within the range of from about 200* C. To about 1000* C., (D) separately recovering the condensable vapors as liquids and the noncondensable gases in a condition suitable for use as chemical feedstocks or as hydrocarbon fuels.

Patent Weil, T; Dzadzic, P; Shih, C; ...

A process for production and recovery of hydrocarbons from whole plants in a form suitable for use as chemical feedstocks or as hydrocarbon energy sources comprises: pulverizing by grinding or chopping the plants to a suitable particle size, drying and preheating the particles in a reducing atmosphere under positive pressure, passing the particles through a thermal conversion zone containing a reducing atmosphere and with a residence time of 1 s to approximately 30 min at approximately 200-1000 degrees, and separately recovering the condensable vapors as liquids and the noncondensable gases in a condition suitable for use as chemical feedstocks ormore »« less
Hydrocarbon- and rubber-producing crops: evaluation of 100 US plant species

Journal Article Buchanan, R; Russell, C - Econ. Bot.; (United States)

Agricultural production of rubber and other hydrocarbons in the United States may be compatible with increased food and fiber production if entire plants are harvested and processed for fiber, protein, and carbohydrate as well. Procedures and criteria have been established for the preliminary evaluation of plant species as potential multi-use hydrocarbon-producing crops. Previously, 106 species representing 44 families and 81 genera were evaluated. Now an additional 100 species respresenting 13 additional families and 60 additional genera have been evaluated, and some of these species also offer promise as future crops. Several Labiatae are high in natural rubber (NR) content: Pycnanthemummore »« less

Fluid catalytic cracking of heavy petroleum fractions

Patent Ford, W; Tatterson, D

A process is disclosed for fluid catalytic cracking in a cracking zone of residuum and other heavy oils comprising gas oil, petroleum residue, reduced and whole crudes, and shale oils with high metals content. The coke deposits on the used cracking catalyst are reduced in amount by regeneration and contaminant metals comprising nickel, vanadium, copper and iron deposited on the used cracking catalyst are deactivated in sufficient amount to reduce hydrogen and coke formation during the cracking process whereby the said catalyst is suitable for re-use. The catalyst particles are contacted with fresh feed and associated recycle feed. The feedmore »« less
Pilot-Scale Testing of an Integrated Circuit for the Extraction of Rare Earth Minerals and Elements from Coal and Coal Byproducts Using Advanced Separation Technologies

Other Honaker, Rick; Werner, Joshua; Yang, Xinbo; ...

The primary objective of this project was to develop and demonstrate an integrated pilot-scale circuitry for recovering high-value rare earth elements (REEs) from coal and coal byproducts. The target performance was to produce a mixed REE product with content of at least two percent by weight on a dry mass basis in a cost-effective and environmentally benign manner. During the first nine months of the project period (Phase 2 Budget Period 2), pilot plant construction was completed including all field site startup activities such as permitting, engineering design, procurement/bidding, unit fabrication, site construction, equipment installation, module assembly, safety training, andmore »« less

A Review on Biomass Torrefaction Process and Product Properties for Energy Applications

Journal Article Tumuluru, Jaya; Sokhansanj, Shahab; Hess, J; ... - Industrial Biotechnology

Torrefaction of biomass can be described as a mild form of pyrolysis at temperatures typically ranging between 200 and 300 C in an inert and reduced environment. Common biomass reactions during torrefaction include devolatilization, depolymerization, and carbonization of hemicellulose, lignin and cellulose. Torrefaction process produces a brown to black solid uniform product and also condensable (water, organics, and lipids) and non condensable gases (CO2, CO, and CH4). Typically during torrefaction, 70% of the mass is retained as a solid product, containing 90% of the initial energy content, and 30% of the lost mass is converted into condensable and non-condensable products.more »« less
