Rates of Reaction of Wyodak Rawhide Coal Hydroxyl Groups with Tetra-alkylammonium Hydroxides and Rates of the Concomitant Swelling

Autor: Glen B. Brons, James J. Isaacs, J. W. Larsen, J. Jones, Ronald Liotta

Publikováno v: Energy & Fuels. 15:769-775

Reaction rates of coals are often limited by the mass transfer rates of reagents into coals. The reaction of tetralkylammonium hydroxides with coals giving coal polyanions is much more rapid than any other derivatization of coal's hydroxyl groups. A

Mechanism of Reboiler Fouling during Reforming

Autor: Glen B. Brons, Irwin A. Wiehe

Publikováno v: Energy & Fuels. 14:2-5

Friedel−Crafts chemistry pathways catalyzed by iron chloride and/or aluminum chloride were determined to be responsible for fouling observed on the shell side of a reformer reboiler unit. Character...

Solvent Deasphalting Effects on Whole Cold Lake Bitumen

Autor: Jimmy M. Yu, Glen B. Brons

Publikováno v: Energy & Fuels. 9:641-647

The more valuable fractions of crude oils can be isolated by removing the heavy-end fractions by solvent separation. The effects of such a separation approach on the quality of bitumen have been studied. Whole bitumen from the Cold Lake region was se

Bitumen chemical changes during aquathermolytic treatments of Cold Lake tar sands

Autor: Glen B. Brons, Michael Siskin

Publikováno v: Fuel. 73:183-191

Cold Lake tar sand samples have been treated in the laboratory in neutral water and caustic brine at 250 ± 3 °C for up to 75 days to simulate the environment during the steam-displacement process used to recover heavy oil (bitumen) from subterranea

Aqueous organic chemistry. 6. Reactivity of hydroxynaphthalenes

Autor: Marudai Balasubramanian, Stephen N. Vaughn, Alan R. Katritzky, Michael Siskin, Glen B. Brons, John V. Greenhill

Publikováno v: Energy & Fuels. 7:589-597

Hydroxyaromatics are abundant in lignite and subbituminous coals. Cleavage of ethers in coals generates additional hydroxyaromatics. Reduction of the carbonyl intermediates of these hydroxyaromatics in 15% formic acid or 15% sodium formate provides h
