1. A chemical reactor, comprising:
a. two or more gas reactor elements, wherein each of the gas reactor element comprises:
i. a first reaction chamber having (1) an upstream end, and (2) a downstream end, wherein the first reaction chamber is defined by a first reactor wall surrounding a first central longitudinal axis, wherein the first reaction chamber has an opening located at the downstream end of the first reaction chamber;
ii. a feed assembly unit, surrounding the first central longitudinal axis and operably connected with the first reaction chamber, wherein the feed assembly unit, comprises: 1) a mixing chamber defined by one or more feed assembly walls surrounding the first central longitudinal axis, wherein the mixing chamber is operably connected to the upstream end of the first reaction chamber, and at least one feed assembly wall is operably connected with the first reactor wall; and 2) two or more feed inlet flow spaces, each in fluid communication with the mixing chamber, and are configured to inject a feed stream into the mixing chamber at radial and/or non-radial direction with regard to the first central longitudinal axis;
b. a second reaction chamber coupled with each of the two or more gas reactor elements, and configured to independently receive two or more product streams from the two or more gas reactor elements, wherein the second reaction chamber has (i) a second central longitudinal axis, (ii) a downstream end, and (iii) an upstream end, and further wherein, the second reaction chamber is defined by:
(1) a second reactor wall surrounding the second central longitudinal axis, and extending from the upstream end of the second reaction chamber to the downstream end of the second reaction chamber;
(2) a bottom plate extending across the second central longitudinal axis, and located at the upstream end of the second reaction chamber, wherein the bottom plate is joined perimetrically with the second reactor wall; further wherein, the opening of each of the first reaction chamber forms a second reaction chamber inlet located at the upstream end of the second reaction chamber so that the first reaction chamber is in fluid communication with the second reaction chamber; and (3) one or more product outlets operably connected with the downstream end of the second reaction chamber; and
wherein, for each of the two or more gas reactor elements, the first reaction chamber has a length ranging from 1 R to 10 R, wherein ‘R’ is a radius of a circle, with the plane of the circle being oriented perpendicular to the first central axis, and the circle having a maximum radius that can be inscribed within the opening located at the downstream end of the first reaction chamber, and further wherein, the angle formed between the first central longitudinal axis and the second central longitudinal axis ranges from including 0° to less than 180°.
