Catalytic upgrading of duckweed biocrude in subcritical water
Bioresource Technology, 2014Herein, a duckweed biocrude produced from the hydrothermal liquefaction of Lemna minor was treated in subcritical water with added H₂. Effects of several different commercially available materials such as Ru/C, Pd/C, Pt/C, Pt/γ-Al₂O₃, Pt/C-sulfide, Rh/γ-Al₂O₃, activated carbon, MoS₂, Mo₂C, Co-Mo/γ-Al₂O₃, and zeolite on the yields of product fractions ...

“Biocrude” and “Biomethane” from Croton bonplandianum
Resources, Conservation and Recycling, 1988Croton bonplandianum, a latex bearing plant, rich in nitrogen phosphorous and potassium (N-P-K), and which grows wild, yields good quantities (12–30%) of “biocrude” defined in the text). This biocrude can be “hydrocracked” to petroleum oil. The seeds of this plant yield 39% oil which can be a diesel oil substitute. The spent residue after extraction of

Hydrothermal liquefaction of paddy straw for biocrude production
Materials Today: Proceedings, 2021Abstract As per the MNRE statistics, the current annual availability of biomass in India is estimated to be 500 million metric tons. Most of the biomass were just dumped, burnt or reused very little. This unexploited potential of biowastes can be converted to an energy rich fuel through hydrothermal processing.

Energy profitability analysis for microalgal biocrude production
Energy, 2013Abstract This work presents the results of a thorough EROEI (Energy Return on Energy Investment) analysis for biocrude production from microalgae processes. We have investigated different alternatives to maximize the energy recoveries of each process considered, which has been modeled and simulated by Aspen Plus™.

Hydrothermal Liquefaction of an Animal Carcass for Biocrude Oil
Energy & Fuels, 2019This study investigated the optimum operating conditions on hydrothermal liquefaction (HTL) for the production of biocrude oil from animal carcass. HTL experiments were carried out at various reaction temperatures (230−350 °C), residence times (10−80 min), solid concentrations (5−20 wt%), and pressures (15−30 MPa).

Survey of biocrude-producing plants from the southwest
Economic Botany, 1982One hundred ninety-five species of plants native to the southwestern United States and northwestern Mexico were surveyed for potential feedstocks for biocrude production in arid lands. Biocrude is the hydrocarbon and hydrocarbonlike chemical fraction of plants which may be extracted by organic solvents and upgraded to liquid fuels and chemical ...

Liquid Fuels by Low-Severity Hydrotreating of Biocrude
1997Bio crude (fast pyrolysis oil from wood) was hydrotreated to minimize the negative aspects of this fuel. The instability of the oil was reduced by reaction of the most unstable functional groups. Concurrently, the oxygenated component of the oil was also reduced, resulting in an improved energy density.

RTP™ Biocrude: A Combustion / Emissions Review
1997The thermochemical conversion of solid biomass wastes to liquid fuels via fast pyrolysis is now firmly established with a number of research, pilot plant and commercial systems producing sufficient quantities for applied combustion tests. Biocrudes produced with Ensyn’s RTP™ technology have undergone characterization and combustion tests in flame ...

Biocrude and solid fuel from laticiferous plants
Biomass, 1986Abstract Stems and leaves of the laticiferous plants: Tabernaemontana divaricata, Euphorbia geniculata, Alstonia scholaris and Thevetia peruviana were studied for their biocrude contents. Acetone and benzene extracts of some of these plant materials were subjected to IR, 1HNMR and 13CNMR spectral analysis.

Biocrude from biomass: pyrolysis of cottonseed cake
Renewable Energy, 2001Abstract Fixed-bed pyrolysis experiments have been conducted on a sample of cottonseed cake to determine the possibility of being a potential source of renewable fuels and chemicals feedstocks, in two different reactors, namely a tubular and a Heinze retort.
