Abstract:
1. A chemical process plant for producing liquid fuel from biogas, said plant comprising: a primary reaction vessel equipped with a first liquid level control means to define minimum and maximum liquid levels, heating means for heating liquid, an inlet gas distributor, a first metallic grid of at least one catalytic transition metal, and a vaporized product outlet port, said inlet gas distributor and said first metallic grid positioned below said minimum liquid level, and said vaporized product outlet port positioned above said maximum liquid level; a supplementary reaction vessel equipped with a second metallic grid of at least one catalytic transition metal arranged to cause said vaporized product to contact said second metallic grid while passing through said supplementary reaction vessel; condenser means arranged to receive said vaporized product emerging from said supplementary reaction vessel and for condensing condensable vapors in said vaporized product; a product vessel equipped with a second liquid level control means to define minimum and maximum liquid levels, said product vessel arranged to receive liquid condensate and uncondensed gas from said condenser means and equipped with a liquid product outlet port below said minimum liquid level and an uncondensed gas outlet port above said maximum liquid level; and pump means for recycling gas from said uncondensed gas outlet port to said primary reaction vessel.
