Eighteen research domains, each with three subtopics, linked by explained relationships. The domains are an editorial taxonomy, not performance ratings of any utility. Relationships are original synthesis. Related sources are shown for context and do not prove a relationship.

Directory of domains

The same 18 domains as a list. Works without hover or the graph.

Domain G / Processing

Pyrolysis and thermal processing

Thermal routes create char and other outputs; every output stream needs accounting.

Subtopics

  • Feedstock thermal suitability. Investigate calorific value, moisture, variability and contaminants.
  • Pyrolysis and gasification. Understand process boundaries and differences among thermal routes.
  • Gas, char and residual handling. Track char, ash, condensates, emissions-control media and gas.

Relationships (3)

  • Constraint

    Feedstock thermal suitability to Pyrolysis and gasification: Calorific value and moisture constrain thermal process selection.

    Question raised: Which limits in G Pyrolysis and thermal processing narrow what G Pyrolysis and thermal processing can do?

    Why connected? (R14)
    Basis: Established engineering or mathematical dependency
    Follows from a definition or balance that can be written as an equation or process definition. No citation is registered, so the statement is general engineering reasoning, not a sourced finding.
    What remains uncertain
    Which limits apply and what their values are depends on jurisdiction and site. No limit values are asserted.
    Direct supporting evidence
    None registered.
    Qualifying or contradictory evidence
    None registered.
    Contextual references (do not establish this relationship)

    Draft analysis (not reviewed)

    Written to be checked, not relied on. No source supports it yet.

    1. Relationship and direction
    Constraint: Feedstock thermal suitability (domain G) to Pyrolysis and gasification (domain G).
    2. Proposed mechanism
    The moisture and energy content of a feedstock affect how much energy is needed to dry and heat it, and whether a thermal process could sustain itself.
    3. Why it matters
    Wet feedstock can make thermal treatment energy-intensive.
    4. What it could change
    Upstream: Drying and feedstock preparation. Downstream: Choice of thermal process and its energy demand.
    5. Source support
    None reviewed. 3 unchecked research leads are queued for review. Leads are not support.
    6. Limits and alternatives
    Whether a process sustains itself depends on its design. It is stated qualitatively here.
    7. What would settle it
    Measured moisture and calorific value of the real feedstock.
  • Material flow

    Pyrolysis and gasification to Gas, char and residual handling: Thermal processing produces char and multiple gas/residual streams.

    Question raised: How does a change in G Pyrolysis and thermal processing alter the amount or character of what reaches G Pyrolysis and thermal processing?

    Why connected? (R15)
    Basis: Established engineering or mathematical dependency
    Follows from a definition or balance that can be written as an equation or process definition. No citation is registered, so the statement is general engineering reasoning, not a sourced finding.
    What remains uncertain
    Which streams actually move, in what amounts and with what composition, depends on the facility. No quantities are asserted.
    Direct supporting evidence
    None registered.
    Qualifying or contradictory evidence
    None registered.
    Contextual references (do not establish this relationship)

    Draft analysis (not reviewed)

    Written to be checked, not relied on. No source supports it yet.

    1. Relationship and direction
    Material flow: Pyrolysis and gasification (domain G) to Gas, char and residual handling (domain G).
    2. Proposed mechanism
    Thermal conversion splits the input into char, gases and other residues, so each output needs handling and accounting.
    3. Why it matters
    All outputs must be tracked, not only the intended product.
    4. What it could change
    Upstream: Operating temperature and residence time. Downstream: Char use, gas treatment and residue disposal.
    5. Source support
    None reviewed. 3 unchecked research leads are queued for review. Leads are not support.
    6. Limits and alternatives
    The output split varies with operating conditions.
    7. What would settle it
    Measured mass of each output stream for each run.
  • Evidence required

    Gas, char and residual handling to Fate, mass balance and verification: Fate proof must include all important process output streams.

    Question raised: What would have to be shown in G Pyrolysis and thermal processing before a claim in H Contaminant fate can be made?

    Why connected? (R16)
    Basis: Editorial systems synthesis
    Editorial systems synthesis supplied in the VRCRI relationship register. No source is registered as direct support, and none is registered as qualifying or contrary.
    What remains uncertain
    What counts as sufficient evidence is set by the relevant regulator, scheme or study design. None is specified here.
    Direct supporting evidence
    None registered.
    Qualifying or contradictory evidence
    None registered.

    Draft analysis (not reviewed)

    Written to be checked, not relied on. No source supports it yet.

    1. Relationship and direction
    Evidence required: Gas, char and residual handling (domain G) to Fate, mass balance and verification (domain H).
    2. Proposed mechanism
    A claim about what happens to a contaminant needs measurement across all significant output streams. Capture in one stream is not the same as destruction.
    3. Why it matters
    It separates demonstrated fate from assumed fate.
    4. What it could change
    Upstream: Sampling of every output stream. Downstream: Any claim about contaminant fate.
    5. Source support
    None reviewed. 4 unchecked research leads are queued for review. Leads are not support.
    6. Limits and alternatives
    Analytical methods for some contaminants are still developing, and mass-balance closure may not be achievable.
    7. What would settle it
    A balance across all outputs, with documented analytical methods.
